Agreed. If they can offer a discount, they always could have.

Business is the art of labor extortion that leads to profits, not the betterment of humanity.

I think there's other reasons why it could be valuable to get the marginal Bitcoiner to spend sats at your business, but it's good food for thought

I can think of several reasons to offer a discount for bitcoin. Added privacy, exchanging usd for kyc free Bitcoin seems to come at about a 2% cost. The cost to exchange USD for Bitcoin also seems to come at a cost of about 2% on cashapp. The question is what is the cost of those USD to the business at that moment... If the business is going to convert it bitcoin anyways (as in they want Bitcoin) there is likely a cost to get it to bitcoin, therefore it makes sense to offer the goods/service at a discount in order to acquire the Bitcoin (potentially kyc free)
