Honest Question about housing prices

What if people looking to buy houses got together and decide not to buy until we make the housing market fall by 40%. If the banks start buying houses we get people to squat so that they don't have a monopoly on all the houses. I was thinking about this because A. Housing cost is really out of reach for people making 60k and B. I remember when all those people on Robinhood app made GameStop and AMC stock go up. Maybe we can manipulate the housing market to make it more affordable.

Do y'all think it's possible?
