What if there is a flaw in the decision software and something goes horribly wrong ? Would not be the first time... The software is written by someone, the decision to use the software was done by someone, etc. Still if really no one else is to blame, then the government is responsible ? So if nobody else then they 'own' it ?
It also means abandoning the risk taking and therefore profit potential / earning power for people.
Challenging.
And once solved why not use the same concept for rental apartments, clothes ?
