I think I'm with you 100% on the land theft.

I'm working on an idea where every citizen would randomly be assigned a half acre of land at birth and those land rights would be non-transferable and expire at their time of death. They could of course rent that land if they wished, but would not be able to sell it.

Also, Ishtar is not directly related to Easter, you're probably better off making a case for Eostre (Ostara).
