Okay fantastic. California and the USA has extremely huge amounts of 'rural area with access to nature'. Enough for everyone with those desires to set up shop. I really don't think anyone would complain at all as many people are already camped on city sidewalks and we tolerate it, so hey, it's a somewhat improvement.

For everyone else, we are in desperate demand of 'inner city high rise'

Sure, you can go homestead in Alaska. That should reduce demand in your city :)

All tent cities in California cities should be relocated to state parks and open space land in unoccupied areas of the state, with homeless services exclusively provided there. They can be housed there while we build housing for the homeless in the more urban areas.

You can go ahead and do that

They aren't mutually exclusive.
