I totally get that there are benefits to a truly untraceable, anonymous currency. But to those who oppose regulation for the simple fact that it's the government getting involved, I would advise taking a look at what happened to the banking industry back in the 1920s and early 1930s before making claims that it's all bad.
Yep. Rules and regulations are usually a byproduct of previous experience. Wildcat banks often issued their own scrip, supposedly based on currency on-deposit, but often that currency was either other wildcat banks' scrip, or was so incredibly over-leveraged that they had really almost nothing on deposit to support their outstanding currency.
These banks could either go under due to bank runs or could just close up shop overnight, leaving the local employees stuck holding the bag while the owners ran off with what real money actually was on deposit. If other banks had this bank's scrip, that scrip was now valueless and that other bank was likely to have its own problems.
