Re: Housing problem
You have not understood what UBI is then!
U = Universal. Means that whether you work or not, you have it. Doing otherwise is just what the state or private insurance pays for unemployment. It does already exist and is not UBI.
Obviously, if you decide you are prefer not working, you won't be able to live in the center of big cities on UBI only. So there won't be any housing issue, or it could marginally push up some prices in remote locations that no ones fancies.
