If someone has allodial title to their property then government cannot tax it. They can only tax property they own and rent out, which is almost all land in the U.S. that hasn't been purchased or confiscated from land owners.
If record of that allodial title is destroyed or lost, then you will have a difficult/impossible time proving you own your land.
