Businesses want to be seen as green these days.
Since the average transaction size of say $50 uses about $1500 of electricity in bitcoin who would want to be seen using it.
Its unsustainable and government will regulate on this at some point.
Do you have sources for those accusations?

and just to be clear: Isn't it irrelevant, whether one sends 1$ or 10.000$? Why do you compare the costs of 1500$ with the amount of the transaction?
Have a nice day!
