For the bitcoin piece of it, I tell them if you don't wanna deal with bitcoin, you can either use this app called fold where you send your bitcoin (like venmo) then they give u a debit card u can spend like any other card and they autocorrect for you.
Or alternatively we can do all the setup for you, cut us in a 3-5% split and we can cash you out into usd periodically.
In the end bitcoin is just the digital money that enables all this. Its like saying you dont like British Pounds. If ppl want to pay you in GBP are you gonna say no and walk away cause you don't like fish and chips?

For the "oh ppl aren't there" you basically answer saying its not about the volume. You're earning way more for significantly less effort. And again its nothing more than what you already do. Its way less effort than getting set up with Spotify for example. Try changing your album art on Spotify, its a whole thing.
Also its a growing ecosystem. You're coming in at the perfect time. Groundwork has already been laid, and you're getting in at the start. As the ecosystem grows, so will the volume
If they have time, I also like to show this:
