Should Christian here do the same thing?
This isn’t a Christian activity, it is a government activity, and it happens in the US a lot, already.
Typically, when a religious or secular group decides that US, state and local law do not apply to it, that it is sovereign in its place, the US government intervenes.
The Branch Davidians, the FLDS (Warren Jeffs), the Nuwaubian Nation, the Sovereign Citizen Movement, etc., all have been stepped on for doing what religions and nations do in Israel, by claiming that they own part of its lands.
