That IS the only reason why churches hands are tied and, believe me, it was not unintentional. No matter who or what you are, if you take money from the government they can dictate anything they want to you. Religious groups should take a stand and be free of government control about anything. Like you said, if it means paying taxes, so be it, it will be well worth it to be rid of the godless intrusion.
I like the idea of unregistered churches and house churches.
Just don’t do anything taxable and your fine.
