[starcraft] Why don't probes warp in units directly?

Why do Protoss even need buildings? Why can't a probe warp in a zealot or dark Templar? Wouldn't that save time and precious vespane gas?

Probes do not have the energy needed to continuously warp in forces necessary for pro-longed conflict. What they do however have are small warp beacons that pinpoints a relatively safe location for buildings to warp in. The energy provided is supplied by the nexus via pylons.
