Good strategy. The "game" has gone on for so long, now -- and become such absurd caricature of itself (apparently without the participants being aware of this fact) -- that it brings to mind the closing line from WarGames:
"Strange game. The only winning move is not to play."
That's demonstrably false. If you're willing to put up with whiteboard tech interviews you have access to companies that enforce them but will pay very highly, regardless of what you consider their merit to be to hiring in general.
Unfortunately one does not, in general, get a job simply by being "willing to put up with" a whiteboarding session or two.
Leaving aside the whole issue of whether actually done properly (or even reasonably).
Again, presenting this neutrally: the quote about the only way to win being not to play is clearly false. If you choose to play (choose to go through the whiteboard circus), you might win (get paid a lot of money at a large and stable tech company). You also might not, but that possibility is there for any interview.
As to the core of what you're saying -- between the lines, the value proposition seems to come down to this: "Yeah, everyone knows by know those whiteboard sessions are mostly bullshit. But hey, if you're willing to swallow your pride and suck it up like everyone else, these companies might throw a little bit of money your way. Coz that's the name of the game, yo -- in case you haven't heard by now."
At some point one gets tired of basing one's life on considerations like that.
