Only pegasus ponies can interact with clouds as if they were solid mass. Since Cloudsdale is made almost entirely of clouds (not to mention the fact it's floating high in the sky), Trixie could not live there or even visit unless she grew a pair of wings.

It isn't mentioned where Trixie lives, but we assume it isn't in Ponyville.
