Hmm... what guarantees mob option will stop existing? That's what's happened with drugs. Drugs are easily available.
Or are you suggesting creating another lender of last resort?
I'm sorry, I'm not sure your offering a solution. It seems what is offered is a blind restriction to satiate your own feelings of 'protecting others'. Like we've done with drugs. It doesn't work because it doesn't address the problem, just the symptom. It's arrogant and short sighted.
