You still contribute to the problem. So what if others cause even more damage. You'll still never convince me it is in any way ethical to profit off of owning somebody else's home. That service you mention? I absolutely disagree that profiting off of another person's need for shelter is a service. It's exploitation. And I can't help but feel like that's pretty much the opposite of a service.

The whole idea is terrible. So sick of a system that rewards greed and punishes altruism.

And, no, the buyer will be the highest bidder, which will likely be a corporation. You want to do some good? Refuse to sell to any company, only to an individual. But then you can't maximize your profit...boo hoo.
