Just to correct one misconception—public key encryption is not the only case where randomness is mandatory. Quite a few other crypto primitives/schemes will fail subtly when used with bad randomness. A nice overview can be found here.

Deterministic public-key encryption is an active research area; for many uses (including common cases, such as key exchange) it actually is feasible.
