I don't suppose they're doing this to make life easier for illegal immigrants who may not have access to debit cards or bank accounts?
If such is the case, someone could design and rollout a cryptocurrency which makes life for illegal immigrants easier. It could end up being the most quickly adopted crypto of all time, no matter how much electricity it utilized, how many animals were harmed or the ecological disasters it might have caused in the process.
As well do not forget, that if you are somehow politically incorrect, often banks/payment providers may refuse to provide services to you. If you have in such case no access to hard cash (or cryptocurrency wallet), you simply cannot live a normal life, as you will not be able to pay even for own groceries.
