Crowdfunded effort (led by the awesome Cards Against Humanity folks) bought a tract of pristine land in Texas near the Mexican border a few years ago to prevent development (such as a border wall), and to leave it in a natural state.

This year, Space X unilaterally started building on the tract, without anyone's permission, causing irreparable harm to the natural state of the land. Not cool, says the owner.

Hilarity currently en-suing. https://www.cahsuesmusk.com/

Elon Musk Owes You $100 • Cards Against Humanity Saves America Day 7

Elon Musk stole your land, and now he owes you $100.

Texas is an interesting venue for this. While it's a mistake to paint with too broad a brush (it's a diverse place), I'd guess that Texas juries (assuming this is a jury case) are likely to set aside their dislike for lefty plaintiffs who try to block border walls in favor of their enthusiasm for enforcing property rights.
@mattblaze the complaint includes a jury trial demand, though obviously there are many steps between here and there
