I think most Bitcoiners would be happy to support a circular economy... but, that's not a very big economy right now. What we need is to convince precoiners that it's in their interest to join that economy. That's not an easy sell to someone who's currently earning 1-2% cashback on their fiat credit - and would instead have to be paying 1-2% or more to CashApp (or whoever) to acquire the Bitcoin in the first place to hand over to the merchant.
