Places like Texas, with a property tax and little zoning, would handle a concentration of wealth better. Although, it'd be even more optional with a land tax instead of a property tax.
We had affordable housing in California in the past without any pie-in-the-sky stuff like land-value taxes.
In fact it would be foolish to buy property in such a market unless you are rich or something limits tax increases.
You're talking about raw communism, whether or not you know it. It is immaterial whether or not land is forcibly taken or the (I assume federal) "land tax" is raised to the degree that no one can afford land except government subsidized high density housing developers. With this being the intent of raising the tax to whatever level it falls.
You may as well just confiscate the land and dispense with the pretense.
Before you begin confiscating land, try proving that inequality issues can be solved with parallel yet less potentially damaging measures. As a test run. For example, begin with educational outcomes. What have been the quantitative results of massive funding toward eliminating educational inequality? Metros like DC have some of the highest per student public school funds in the Nation.
The housing parallel is the failed social history of high density urban "projects". Which no one likes to live in nor to be around. And which have been a disaster for urban areas, with few exceptions.

Explain how government forced divestment from single family private land ownership is capitalism. Other than communism, you seem to be thinking of a potential action inherent within fascism.

Some of this might have been because of the impression Georgism had on some of the Chinese revolutionaries, including Sun Yat-Sen himself:

It's also because, by coincidence, U.S. State Department official Wolf Ladejinsky was influenced by Georgism. He was certainly no fan of communism, as he was a Ukrainian refugee from Bolshevik rule!

Incidentally, while Taiwan does not have exclusive government ownership of land unlike Singapore, Hong Kong, or mainland China, it is a very successful example of land reform (which involved confiscation):

So don't dismiss that tech workers are a proximate cause here.

For another, look at the history of the city, we have been a nut house for ~150 years, since the gold was discovered. We had an Emperor! https://en.wikipedia.org/wiki/Emperor_Norton
It's pretty obvious on the ground in SF that the homeless problem is fundamentally a problem of mental illness and drug abuse. A fairly large portion of the homeless there are not from SF but came there because SF tolerates behavior other cities do not. Even if there was an empty, free house offered to every homeless person in SF there would still be a massive problem because many of them would be unwilling to accept it.
If society thought of housing similarly to other large purchases like cars in that there was no expectation of profit, we would all be a lot better off.
Now what caused this housing as investment idea? I haven’t seen any research on this, but my guess would be as a form of forced retirement savings as it allows people to build net worth without the self-control normally required of saving. And the difficulty of that delayed gratification is really just human nature.
And you don't get margin called.
150x leverage means 150x cashflow burden from taxation (> 100%!) and also maintenance costs of the property.
See https://news.ycombinator.com/item?id=35044028 where I laid out how a real estate purchase is really a mix of multiple investments packaged into one sale.
To what extent the crime policies contribute statistically I don't know, but for some of the more extreme mental illness cases (that disproportionately account for homeless people being actively aggressive), there is a disconnect between philosophical ideals and what practically would be better for everyone in the long run. Mental illness (especially when substance abuse is involved) can make someone resist help and they will be unlikely to improve unless they are forced into a facility. Where the line is for doing this is a tough question but if someone is routinely threatening people on the street or does something violent, it seems like SF policy is still opposed to it.
I don't think people realize how much of an outlier SF is. Incomes are a good 25% or so higher than NYC and Boston. The percentage of the people who work in tech in SF isn't really comparably to any other city and their own high paying industries.
I think the problems with SF are largely cultural and political rather than technological or economic, though the economic issues are exacerbating it. It's an "anything goes" city and has been for 150+ years. The city values your ability to express yourself in any way you please, and that includes both healthy forms like street fairs, neighborhood scavenger hunts, or Bring Your Own Big Wheel, and less-healthy forms like being able to shit on the sidewalk when you please or stab someone who looks at you funny. And that filters down to the voting preferences of the electorate. You get what you ask for.
The South Bay has all the same problems of tech dominance, income inequality, insane housing prices, etc, but the cultural orientation is very different. People in the South Bay are generally there to work hard and build a better life for themselves and their descendants. Their time-orientation is much more long-term than SF culture. And that applies across the income spectrum - even poor, Hispanic, immigrant day-workers will do their best to make sure their kids do their homework. The type of tech industry that spills out of this also reflects this cultural orientation, with the South Bay doing much more foundational engineering research and SF being more focused on how to apply technical breakthroughs from 50 miles south in new and crazy ways.
Of course, when you bring up Manhattanizing Mission, most of these "YIMBY" astro-turf types start screeching. They want theirs, and as soon as they get it they'll be pulling up the ladder behind them. But keep your filthy mittens off the Mission.
