Should Taiwan BUY SAMs over fighters?

This gentleman makes a good point. Is it time Taiwan cut back or gave up its fighter force? Should they double down on fighters, and press for F-35 or even AV-8?
What about paying a F-35 partner nation a high price for 30+ F-35s? Pay the partner extra, then have THEM order the Jets?
IS TAIWAN DOOMED no matter what?
