I've had a draft on the back burner for a while comparing the Luddite revolution of the 19th century to the IWW-led strikes of the 20th century and how breaking private property was a key strategy in both, and how they both fell apart only after violence against people was brought up. I'm not sure what the 21st century example would be, maybe not having a large labor movement anymore means there isn't one. I still can't quite get my thoughts together and haven't gotten very far on this.
