That whole comment is "With a way harder method than going to the ATM".
I understand that it's possible to get crypto through obscure methods. However if you're selling a privacy focused solution, ideally you shouldn't have to spend 3-4 weeks to acquire the funds to purchase it.
I agree cash is currently king, but we need a crypto (or even better, Monero) economy if we are going to maintain financial privacy in the long run. In the event of a full transition to a Central Bank Digital Currency, like the EU is discussing and Brazil has already announced, cash will not be private anymore, as any physical bills will be just tokens for the underlying digital currency, which is tracked by the government.
