I do not believe that the only way to play is to always be at 100% and that PCs should never be disadvantaged in some way.
I'd go so far as to say that by rejecting magic marts and WBL, etc, 5e represents a deliberate step away from that concept.
You're not intended to have an item for every problem, nor is it assumed that you will.
Again, though, a DM can override this on a per table basis. So I hope we didn't skip that step just to make a case for magic shops.
