11. Yes we can and should do both

As for your other point, I go back to two things:

1) Death of the WW2 generation. Newer generations take democracy for granted and don't know the dangers of other systems and don't know history all that well in general.
2) Covid and lockdowns really accelerated conspiracy theories and general selfishness.

Both of those factors make our systems very vulnerable. People don't seem to care that our institutions are being destroyed; they just want "change" and they want it now.
