Alright, the leasehold is the "bail emphytéotique", apply to land easily and ensure its return with whatever was built on, that way no alien to the island can buy any land and can later enforce a ban on any new freehold sale that way those that have bought can end with the obligation when they want to sell to their property lto do so leasehold knowing that the new state or Land council under a very large autonomy will automatically recover the land's right. Land recover that way could be used to fund the program to build free homes for the native population.
