If you are heavily invest in Bitcoin outside of your IRA it could make sense to not have Bitcoin in your IRA as a hedge in case Bitcoin fails. That being said, you could always have a small percentage of Bitcoin in your IRA as well but that would be the argument to not be heavily invested within your IRA. 

Same idea as not selling your house for Bitcoin. Safety net in case something goes horribly wrong.

I agree with your statement - but what I'm looking for is arguments about why I should not put BTC ETFs into my IRA

Any Arguments Against Bitcoin ?

Anti bitcoin arguments are irrelevant in this case because there is no argument for why people shouldn't have access to purchase Bitcoin if they want to. Gatekeeping is stupid. So regardless of ones stance on Bitcoin why stay with a provider that wants to act as a condescending parent. They work for you, not the other way around.
