It would also cost a lot less if we forced all criminals to work for free (though right now, they practically work for free). The problem is that we would quickly run out of criminals since there are so many projects that needs work. We could just randomly enslave people to do work for free.
Enslaving citizens wouldn't be fair or popular with the citizens of our country. Another option is to use our military might to subjugate other countries and bring them over to work, say to work on our farms. That would allow for very high gdp growth.
So where do we draw the line and who gets to draw that line?
Surely somewhere we can accept that a bunch of wealthy playing the investment game on very limited resources instead of the realm of producing solutions or improvements isn't the way to further society as a whole. We don't have to put down those already in the ditches further, we got a swat of people above to look at.
Eliminating NIMBYism and individuals' selfish obstinacy does not need to lead to a global hegemony enslaving billions.
And the absurd examples you tried to come up with are literally things the US is doing today, you're just being sinophobic.
If you offer the group a certain percentage of market value, that could work out well. But unanimous consensus is not a reasonable way to get land for big public projects.
“Market value” requires willing participants. If a seller doesn’t want to sell at a particular price and the good isn’t fungible (which housing is not), they aren’t getting market value by being forced to sell at a price determined solely by the buyer.
If you think it's impossible to assess the value of a property, the whole legal world disagrees with you.
And yeah, the point of eminent domain is to force the sale on unwilling participants. If used sparingly and without discrimination, it's a good power, and part of living in a community that will undertake community projects.
* the underlying assessed value, excluding artificial caps like prop 13
FMV +10% for tolerance of estimate of FMV + 6 months average salary in the area would be generous enough to recompense the hassles of relocating.
Remember surrounding society, that is hundreds of thousands of other people, benefit from the infrastructure being developed.
I think by phrasing the holdouts as "hold hostage over public projects" is misguided if not disingenuous. This is a common propaganda used by authoritarian regimes to paint anyone they don't like in a bad light: surely they're not victims of government brutality if they're "enemies of the common good."
But if we accept we can discard one individual's (or a small group of individuals') rights, then it's not long before everyone's rights become disposable. That's how people like Putin and Xi justifies their aggression (surely I can kill millions of people in Taiwan if it stands in the way of "progress" of 1.3 billion mainlanders!)
P.S. As someone as pointed out, this is not a China/US or eastern/western issue. The U.S. has its own fair share of blatant violation of private rights too.
But my point is that it's wrong when U.S. does it, it's wrong when China does it, it's wrong when anyone does it and it shouldn't be something we aspire to.
