> There's a lot of investment that goes into building community relationships and the living space itself that doesn't translate into market value.
My proposed solution preserves community relationships.
> So you're making an ethical appeal that old people should be forced to sell their homes to solve homelessness
Nope. I'm arguing that people shouldn't be able to use zoning to wield power over other people's property to the unreasonable extent we're seeing now. That they can do so is a result of laws like Prop 13 - there's no personal cost to being anti-development.
> People are living on the streets because they can't afford housing, because too many techies are moving into town
You're literally arguing that no city should ever increase in population - it should stay frozen forever because god forbid, otherwise the neighborhood might change.
> Young people living in a fun adult playground
What does that have to do with higher rent and property prices? Or anything else?
> Now which is more important: helping wealthier people live in a funner city or keeping seniors in their homes? What's the first priority here?
You can do both and have no homelessness. Oppressive zoning laws prevent it.
