I don't consider loan guarantees to be 'bailed out', while I agree that the effect is still largely the same. The US gov't providing loan guarantees now will all depend on the faith afforded the US Treasury. The percentage of takedown by primary dealers in all auctions over the past few years is exorbitant, and being flipped right back to the Fed within days. The largest source of "confidence" in regards to Treasury bonds, now, is the Federal Reserve via PDs.
How much more can the fed balance sheet explode before retail and institutional investors put on the brakes. I guess that will be determined by how long we dump $85b per month in liquidity into the markets and how long we can get away with direct monetization. Sooner or later, the gig is up.
