<Snipped quote by Earnest Evans>

One wonders how you're supposed to earn a significant amount of money selling real estate in the multiverse. It isn't as if land is hard to come by.

It's really good land, and it's primarily sold to the worlds' residents. Shocker+ comes into a place in crisis, eliminates the threats to it, and politely takes over for taxes and rent. 

The worst thing about land in the multiverse is the fact that a large majority of it is undeveloped. Log-cabin subsistence farming is fun for some, but not for others.
