There are probably some benevolent communes, although I'd certainly be wary of investing much in building up "free" commune land knowing that you're basically acting on faith the owner doesn't simply declare everything you've built is "the peoples" and then use his position as glorious leader to lord it over you.

Based on how much people pay for even absolute shithole desert wasteland where I live, I can tell you there'd be a huge demand for homesteading federal BLM or other land if they'd reopen it. It would definitely help people who can't afford to get land on their own.
