Is that a "but" or is that how things should work? You solve a problem when you have it or can reasonably predict it (in technical/engineering terms). I also think it's sensible to look for experts when you need them right?
I don't know I've been places where the difficulty scaling and failure to do it promptly posed an existential threat. As in "this system is poorly designed and needs to be rewritten so we're going to pause new features for six months to do it", you can't always just magically find an expert to solve your problems in a timely manner, and feeding the technical debt monster can easily kill startups.
