I don't really get why you seem to believe there are just two extremes and that's it. I don't think "do it right from day one" means that you never accumulate technical debt or that you write the perfect architecture that anticipates every possible future need.

Doing it right, to me, means hiring people who can adapt to changing conditions and needs, and who can make (or help you make) the right trade offs when you have to balance faster time-to-market (which can involve cutting corners) against avoiding technical debt.

The team that lives inside IntelliJ and can't do anything outside it is not going to do that for you.
