Hell, my experience in life is that everything is harder and takes longer than you think it will. You can normally count on this by figuring how long you think something will take, then add a third. That third will often save your ass.
As far as market readjustments following a universal revaluation, the more realistic timeline is six months to a year. This is something like a preventive surgery to eradicate a tumor, and it takes time to recover.
Still, I think my logic is sound. We let the actual people do what the banks do for themselves all the time.
