There is no rental trap. The problem is runaway inflation that destroys savings and taxes investment gains. The only reason housing is such a good deal is that the first 500k is tax free.
Your decree does not invalidate the lived experiences of the people who want to own a home but can't afford the > $80k down payment, so they are stuck paying rent. The problem is credit inflates housing prices. Some parties, such as speculators, have plenty of credit, so they can buy multiple houses & inflate the markets using credit. Those who cannot obtain credit or are not willing to play the game are stuck trying to save up > $80k for the down payment on top of their regular living expenses that are under rapid inflation.
The middle class used to be able to buy a home or large acreage outright without credit.
