I’ve seen this argument before, and can’t help to think how naive it sounds.
Can you name one other case where the fact that we don’t want something to fail results in it being unable to fail?
Actions have consequences. No matter how much we don’t want a particular set of consequences to occur, they will if we perform the wrong actions.
The US dollar will continue to be supreme so long as the United States controls the US Agency for International Development, the Office of Foreign Asset Control, and the US Marine Corps.

I would prefer reasonable home prices, which means neither collapse nor bubble mania.
But it's not house prices that are important. It's housing affordability, which is better measured by monthly mortgage payments (and rents).
However, that was not what happened in and after 2008.
Availability of credit collapsed. So owning housing got cheaper for people who could still get credit, but renting did not become cheaper. Have a look at the backlog of https://www.idiosyncraticwhisk.com/ for more than you ever wanted to know about the topic. (Or splurge on the author's book.)
