No, you have to be a Jack-Mormon, aka a Fundamentalist Mormon. And in fact their group thinks polygamy is fine, but not polyandry. Gotta get rid of Ben first.

If you want a legal plural marriage, you need to move to a Muslim country, but keep an eye on our Supreme Court. Religion seems to trump everything else for them, so I would not be surprised if they rule for the Jack-Mormons in the future. And for rich immigrating Muslims who want to bring all their wives.

Educating anyone benefits everyone.
