Maybe their stock portfolios (for the few who have those outside of 401k's) take a hit. But the key is that if there's a real estate downturn, almost every single home (house, condo and even land) takes a hit and so you end up with a situation where all the inventory drops in price, but not all the eligible buyers "drop in price" (i.e., not all eligible buyers suffer a downturn and so, net, you actually get more people into homes).
The key of course is that the downturn isn't so massive (hello 2008!), where the blood flows so freely that the layoffs/foreclosures/etc. overwhelm the eligible buyer pool in absolute numbers. That can for sure happen, but is atypical historically.
You've just listed a set of specific circumstances under which some number of people might find housing more affordable, but that's a lot more like "investment outperformance" driven affordability than "broad based housing price decrease" affordability. That can happen even without a recession. A small number of people could've found Bay Area houses more affordable in the last decade if they were HODLing some 10x stock.
