I think it depends on how much you're going to beat up the bike in the interim. If you're concerned about the effects on the resale value in six months, don't tape it. If you're thinking about the resale value after five+ years of commuting, it probably won't hurt and might even help since it's another layer of protection from the elements.
FWIW though, I would NOT want to have to take the tape off of mine... that would certainly be no picnic. Like I said, it has admirably withstood several years of duty as a beater bike year round in Boston and isn't so much as peeling.
