The market based solution is already present in city streets today with mentally ill, drug addicted, and others (under employed) living in tents and cardboard (or their illegally parked vehicles).
Once their UBI payday loans are properly directly deposited to a bank to repay last week's debt, they can once again return there. The idea that the most downtrodden will be better with their finances than 80% of the rest of the population is laughable.
Rental means paying the costs of property plus paying profit to someone who is already well off enough to front some capital (or at least to get a mortgage) plus paying profits for the bank ... how could renting ever be reasonable priced in a system that requires those without capital to pay those with capital just because those with money already have enough money.
landlords aren't guaranteed to make money. it's true that monthly rent is almost always higher than the monthly mortgage payment on that property, but the landlord can only profit if, in the long run, the difference between the rent and the mortgage is greater than the overall cost of maintenance and possible devaluation of the property.
personally, I could afford to put a down payment on a mortgage if I really wanted a house where I live, but for now I am happy to pay extra for the ability to relocate at the end of the lease and to avoid the risk of actually owning a house.
We just about made a profit on the flat - about £10 a week, but we didn’t have any times of no tenant, or any unexpected major bills.
Eventually price recovered enough that we could afford to sell (below what we paid, even ignoring inflation).
Not all landlords are raking it in.
When rent is taken care of (cause there isn't rent), along with food, water, electricity, communication and more, what is there to 'buy'?
Clothes, cars, boats, planes, watches, electronics, vacations, fancy meals, you name it...
Also, I have to point out, if you had made that list a hundred years ago, electricity wouldn't have been on it. Luxuries have a way of becoming necessities.
Perhaps a more relevant example: Look at the bottled water industry. Even if all our creature comforts are provided for free, someone will pay for a "premium" version.
