You can't have too many tools, for sure.
You can, however, have to little space to use them.
Given I live in an apartment and like to avoid annoying my neighbours, I don't use power tools all that much.
I mostly use rasps, scrapers, hand plane and sandpaper.
I have a drill press, a hand-held belt sander and planer - too noisy for regular use where I live.
Doing stuff by hand is much more satisfying anyway, IMHO
