In this case you wouldn't be able to move anywhere because every army (including spawned 1-unit rebells) within three provinces distance would block you from leaving your cities. Even worse: the towns in rebell or hostile provinces would make it impossible for you to move.

The better sollution would be to reduce the real time per turn to a level where it matches with the movement allowance. But in this case the game would last several thousand turns.
