My feedback: until the moment I click the "order" button, do not require me to log in. If "Checkout As Guest" can possibly be sufficient, at least for the "Grid Proto" tier, then do that.
You have a digital payment instrument for the order regardless of login. That should be sufficient for whatever legal obligations exist, real or imagined, so have the courage to make that policy despite the pushback.
