In Hawaii you cannot have house churches because it violates the zoning code.
They cannot outlaw that. And if I opt to have a few friends over for visit on Sunday, they cannot outlaw that.
The problem is that contemporary "Christians" are so wedded to the corporate/business model of "worship" and "Chrisianity", that they are unable to function without some highly paid/poorly paid religious professional/synod/wahtever telling them what they have to believe or practice.
Get away from ritual. "Call no man father", etc. Find out what God wants from and for, you!
That's what freedom of religion guarantees. They can't outlaw that.
