I agree. It will be horrible, and most people, including myself, are not ready for the negative consequences. We're also not ready for the inevitible collapse due to hyperinflation. People aren't even prepared for inflation, as it is. They're just on autopilot, hoping that everything will be ok, as their savings are hollowed out.
But, I'm also optimistic. The ability for humans to adapt and keep prospering against all odds is amazing.
As far as ending the Fed, similar arguments were made against ending slavery in the US. "It will destroy the economy and upend the country through civil war." And, it did. But, we recovered.
Ask yourself, will the masses ever be prepared for the painful phases you suggest? Should doing the right thing be abandoned because it will be hard? Are the consequences of controlled, proactive change (changing the system or creating a parallel one) better than that of sudden, reactive change (system collapse)?
The country was founded on "Live Free or Die." People had courage to risk it all, because they knew the consequences of not acting. Today, the propoganda is so effective that people are unware of the problem, that we're driving towards a cliff.
When the collapse does happen, they will scream "Why didn't we do something earlier?"
