It is absurd that somebody is paying $550/month to live in a place without running water. In under 2 months I built a cabin for under $500 and have enough space to grow a garden.
I am very in favor of Georgist style land taxation.
> There is more than enough land for everyone to have a small chunk. With technology it is easy to be connected and employed anywhere.
Anywhere there are utilities. Also, who decides how those chunks are allocated? Who gets a chunk in Monaco and who gets one in the New Mexico desert?
Henry George has some good ideas on valuing and taxing land. Maybe even negatively taxing the worse land.
You're missing the point. The reason why housing is expensive is not the lack of available land. The reason why housing is expensive is due to the fact that a lot of people want to live in and around very specific locations and don't want to waste time commuting to and from those locations.
The other half of the answer is that (in short) we've created a set of legal structures to prevent land owners from building the amount of housing that the market would otherwise build on their own land.
The scarcity, and thus value, comes from excluding people.
There actually is a lack of affordable land. Rural land has been amalgamated by the agriculture companies, timber companies, and government. Buying rural land usually has to be done in large acreages and it is still expensive.
