Performing backups of our production apps used to take hours (especially in cheap clouds) because of all the loose files. Today, it takes about 3-5 minutes since there are just a handful of consolidated files to worry about.
There is zero reason a process would have more than tiny slowdowns with even millions of files in a folder. Finder has problems if you're trying to look at that folder, for obvious reasons, but it's a bit of a self-own for a backup co to claim that 200,000 files causes their solution to break. That speaks to serious algorithmic issues.

We're small fish here but I'd imagine if we're thinking like this, larger companies must certainly be at least taking this into consideration. In effect, this is The State attempting to Price Fix around jobs-of-a-feather. No matter the intention, this is not The States business.
The only possible purpose of making laws like this is so that the state can try to enforce some remedy whereby we're told how much we have to or are allowed to pay someone. Who in their right mind wants to sign up for that kind of risk?
EDIT: When I say "one more reason" I mean specifically CA, its simply not cost effective to hire talent from there. CA taxes and cost of living are such that making a competitive offer to a candidate residing there is simply too costly from a compensation perspective. Plenty of people-talent exists in states with more favorable cost of living and tax schemes.
Is for pay transparency. And in the vast, overwhelming percentage of the time, an employer knows precisely what they're planning to pay for a role, with extremely little variance. These cherry picked examples don't really mean a lot.
As to your imaginary firm not hiring in "CA, CO or WA", absolutely nothing was lost by the residents of those states.
