Pabst,
In a perfect world, you might be correct. We live however in a world where businessmen are capitalists when things are good and socialists when they turn sour. Unemployment is far less than the average during the last 30 years and people act like we are in the Great Depression. People are outraged that the banks expect payment on the no money down, no doc,liars mortgages they took out to buy $1million properties with no job and no assets, and in many cases, no legal residency. Congress' reaction is to freeze foreclosures and let deadbeats live free in houses they never should have been allowed to buy in the first place.
So you have to accept as a given that the government is never going to let the system flush itself. The irresponsible will be bailed out, whether they are lenders or borrowers. At the end of the day, all Bernanke is doing is lowering the cost of the bailout by preventing a total credit seize-up. The results will be pretty much the same whether we pump money in through the Fed or let congress piss it away on stimulus packages and bailouts. Of course the dollar gets trashed, but since europe will soon be doing the same thing , it won't be all that terrible. The dollar actually appeared to stabilize last week.
As for inflation, all politicians deeply believe that it is far preferable to deflation. Moreover, it is true that much of the commodity inflation is not a Fed-created problem. Chinese demand coupled with an insane ethanol policy should get plenty of credit. War in the middle east and a congress that won't allow drilling and blocks new coal and nuclear plants don't help.
Bottom line I agree that Bernanke has been a disaster. My reasons differ from yours however. I feel he should have recognized that there was a serious problem developing in the housing/mortgage/CMO sector and brought rates down more quickly.
