If you have a friend who is already running their own BTCPay instance, then I absolutely agree with you but I don't think that is the case for most new to bitcoin. 

Geyser is a great place to learn with minimal fees and they can get plugged into the community of bitcoiners looking to help orange pill new users and launch new projects. 

Not really. You can connect to someone’s instance and create a e-shop in a matter of minutes.
Geyser does not seems the correct option for a e-shop imo.

I would start with Geyser before a BTCPay instance. That's a lot of technical lifting for a brand new user.
