The energy that goes into a Bitcoin transaction doesn't just pay for the one transaction. It also pays for the security of all the value stored in the rest of the system, and that's actually where most of the revenue for mining comes from - inflation, not fees.

But also, Bitcoin transactions aren't typically buying coffee from your local store. It's very often international, and Bitcoin transactions offer a finality and immediateness that can't be found in other financial systems.

But also, in many cases Bitcoin is your only choice to transact at all. Our business keeps getting rejected by payment processors such as Stripe and PayPal, and at this point Bitcoin is our only option to get revenue from Europe. As a result, Bitcoin is making things possible for us and our users that simply aren't possible at all without Bitcoin.

If you think the fees are absurd, make a system that gives all the same benefits to us without costing so much. So far, we don't have an alternative, and we are very grateful that Bitcoin exists as an option.
