Lots and lots of companies have completely embraced remote work. You are not hearing from them because once they embraced it they found people better than you [1] who'll work for a tenth of the price. In other words, offshore.
Put another way, you're only seeing Office-work positions, because once they grasp that the job can be done remotely, they grasp that you're expensive.
I know, I know, soooo many reasons they should pay more to get you. On the other hand the entire manufacturing industry figured out "remote manufacturing" means cheap labor...
[1] obviously I'm speaking generally because I don't know you. But statistically it's likely to be true.
