... A reasonable limit...
with this statement you are establishing regulations. You may not mean it intentionally, but you're calling for no regulations and then contradicting your original petition by saying this should be a rule. While I do agree that regulations should be toned down, I just wanted to point out this issue that I noticed.OK maybe I was not clear enough. In many places there is a limit for cash transactions to prevent money laundering. For example in Germany shops can accept up to 10 000 EUR in cash, per day and per customer, without ID. No problem for normal people, but certainly a hurdle for a criminal with a suitcase full of cash
So the existing limits of that nature (typically $10K or 10K EUR) are fine. A store could take $10 000 from each customer, daily, and convert it into BTC. Trouble is, the legislation and justice system is so hostile against BTC that no one can do that in practice...
Example is that Florida case. AML limit is $10K but the other law really limits cash transactions to $299. Or zero, if the buyer makes a dumb joke. Not cool...
