Of course they won't get evicted, which makes the whole idea of paying "rent" useless if you're trying show them that financial responsibility is important and consequential. Again, I see no reason to do this when you could just have them pay for their own toys if you really want to instill that. Even the ipad and wifi access is fine, I guess, given that's like a legit privilege for a 7yo. But imposing a landlord/tenant dynamic over the parent/child one at such a developmental stage, even as superficial as it is in this example, is bound to cause some issues in the relationship later on.
