That's completely inefficient. Its not like they don't have sensors or warning signs. There's no point in having huge armads protect federation worlds that lie far from any border and therefore any threat, ships are needed to patrol borders where threats might arise.
Pardon me, but how often has the Earth been targeted for destruction and the Enterprise been the only ship within range?
Its really just a tv show, its pointless even discussing this kinda stuff.
