It doesn't seem like the "Liberland" people have any claim to the territory, but I don't think that makes my point misleading.

If Croatia says the territory belongs to Serbia, then Croatia has no business sending police there outside of very narrow circumstances such as people there launching attacks into territory Croatia does claim. On the other hand, Croatia would probably be within its rights to enforce a border with this territory, as would Serbia. That would rapidly become unpleasant for anyone trying to live there.

The Liberland people are exactly claiming the land, that's the whole point of what they're doing.

Croatia, even if it claims the land is Serbia, consistent with its border claim, it still administers it as a practical matter, that includes keeping people out of where they shouldn't be.
