This isn't about scale, it's about location. Ecuador is a LOT more powerful than you are, but assuming you are not currently in Ecuador and don't have any bank accounts in Ecuador, how do you think they could seize any of your assets, if they had a mind to? Their options start (and very nearly end) at "sending you a polite request".

The backstory here is, Chevron used to have a lot of assets in Ecuador as part of a joint venture with the Ecuador state oil company. The joint venture wound up, Chevron left, and now there's some dispute over whether any remaining clean-up is properly the responsibility of Chevron or Ecuador. But this is being discussed after they closed everything down, sold up, and left.

All that's left if for Ecuador to go try and convince the legal system of other countries (where Chevron does have assets) to do something. And so far, that's not working very well for them.
