> Your productivity being high with a given tech stack does not disqualify an alternative tech stack from having equally high (or much higher) productivity for equally trained users.

Certainly you can do it, just as you can build a house with a hammer and nails rather than a nail gun.

But you'll spend lots of time building undifferentiated infrastructure that you could have got out of the box.
