"Boxing out the next generation" is exactly what the law is for. I guess we have to decide whether we want more natural wilderness or more luxury homes with nice views.
The only way I can think of to preserve the wilderness without any isolated homes for the wealthy is for the government to buy up the land. I'd probably support that, if we could get it done, but it does mean that if the money for it comes out of the general fund, then you probably have average people paying for more of it, instead of mostly the wealthy.
