You've got to realize that the Puget Sound region is an absolute outlier in every way, the perfect storm of restrictive geography with a high concentration of very successful companies. The only options are:
-- Reach a point in your career where you have the money to play the game.
-- Move farther and farther out from Seattle, somehow finding a way to put up with the commute.
-- Go full on remote. There are puddle jumper flights to lots of small towns in eastern Washington. You could buy a place here for half (or less) the cost of Seattle, hop a plane when needed (shorter flight than your Puget Sound commute), and otherwise work remotely. Not an option for everyone, I know, but for some it could be a real win (It worked for me when I decided Seattle was too expensive 12 years ago)
