But it seems more useful to me to calculate P(hypothesis | data).

That may be true if you have little influence over what data is available.

Frequentists are mainly interested in situations where they can create experiments that cause P(hypothesis) to approach 0 or 1. The p-value is intended to be good at deciding whether the hypothesis has been adequately tested, not at deciding whether to believe the hypothesis given crappy data.
