Depends how they are taxes.  Most of them are making poverty income and would shutter when they couldn't pay property taxes.   I imagine the remaining ones would be more commercialized,  designed to spend more time bilking grandma and more time on lowest common denominator rabble rousing as that generates the most income.

Non profits already don't have to pay property taxes. So if the church qualifies for non profit status under normal rules, little would change in that regard except reporting requirements.
