Vonovia is the largest landlord in Germany, with >1mn tenants and >565k housing units under its ownership. If, say, tomorrow, we were to simply destroy the contracts where renters are renting a flat, and trade them for ownership (i.e. outright giving away the flats to their current tenants), we could literally solve the life of a million people at 0 cost to anyone except the stockholders of that god-forsaken firm. Any moral ideology which doesn't support doing this immediately is clearly acting against morality.
