I believe we already have similar laws. Idle land can be claimed by people who live on it after a length of time.
You're talking about adverse possession, I think. That's not the same thing. That is just a statute of limitations which says that if you possess land thinking it's yours, and someone shows up one day claiming it's his, you can keep it if you've had possession for a long enough time, because the statute of limitations for the opposing party's claim has passed.
Chavez is simply trying to take land from people who aren't using it. Different animal.

I can't speak for the rest of the country, but in California squatters have no rights *unless* they have paid the taxes on the otherwise unencumbered property for five consecutive years. Recorded deeds of Trust have primacy in order of filing subject to subjugation regardless of this point of Title Law.
