Georgism has interesting extensions. I see the core point as things that were originally allocated arbitrarily/with force should be taxed highly. If your ancestor was a knight who seized some land by force you should have to compensate the rest of society to keep it. You can extend it to pollution. Polluting is taking some of a common resource (the environment) from everyone else, so polluters should compensate society proportionately. You could even extend it to network effects in tech. If you have users just because you were first and made it hard to leave, that's something unearned you took from society that you should compensate us for. I think this one is more of a stretch and sadly probably wrong.
