Exactly. That's why it's ineffective to evangelize this as individual effort. If you want to live in a multifamily home, they have to be zoned, funded, and built. That requires lobbying the government, moral rectitude.
I did not write 'individual habits' - you did. Things like zoning are not individual choices at all. But they are something that you and a few friends might be able to influence at city hall.
