Except churches would still be tax-exempt. All they would have to do is make their finances public, so that the people donating money to them know what that money is going towards. If they don't want their congregations to know how much they spent building a giant mall or buying private jets, then they can choose to pay taxes instead. If you don't think your congregation will care about the private jets, then by all means, keep your tax exempt status.
