Re: Louisiana petitions Obama for secession.
If Puerto Rico were to become a independent nation, I would have trouble seeing them being "charged" for land prior to their departure. So why would Louisiana?
The Federated States of Micronesia were not (apparently) charged anything
stemming from their departure.
Louisiana is not under the same arrangement as Puerto Rico or Micronesia (at least, not yet, in Puerto Rico's case), so it's not an apt comparison. And I don't see Louisiana seceding under amicable circumstances where the government would be inclined to be generous.

Nothing beside remains. Round the decay
Of that colossal wreck, boundless and bare
The lone and level sands stretch far away.
