It sounds like you're talking about taking cash to your bank and depositing it into your own bank account, which of course you can do. The original commenter was talking about taking cash to your bank and somehow very quickly distributing it to everyone you owe money to this month.
The original commenter is talking about a solution which would be vulnerable to the exact sort of "digital jail" being referenced in the article. They've added a central authority to their decentralized solution, in the form of the absolute classic way banks are used against people - by freezing accounts and deposits etc.
Nah, because you can just go to any money transmitter. Which is actually just anyone, if we didn't scare people off it by making payments this like, scary bureaucratic taxy AML'y thing.
I have online banking on my phone, if you wanna give me cash to send it to someone, no problem, why not.
