It is disingenuous of you to dismiss a scholary article/magazine because of it's slant. I have never in my life met a politically neutral economist dismissing the piece because of how the paper leans is unfair. Therefore, your counterargument should suffer the same fate.
It is disingenuous to describe The American Spectator as scholarly. It is a news opinion and commentary magazine. That's like calling the Huffington Post scholarly. Scholarly articles are subject to external review by objective evaluators, which this was clearly not.
So yes, I will dismiss an unreviewed piece in a right wing political advocacy magazine as one that, to be charitable, perhaps does not give the most accurate or unbiased evaluation of the causes of the financial crisis. You should also reconsider taking information from openly biased sources more skeptically.
As far as the GSEs are concerned, the underlying changes in the 1990s did great damage, as mentioned in the article. Furthermore, government turned a blind eye to the packaging of contracts and the relevant algorithms because it complemented their home-ownership policy. This allowed banks to spread the risk and Uncle Sam cheered them on. All the regulatory bodies looked at these contracts and gave them a thumbs up.
Saying that the government is at fault instead of the banks because it didn't stop them from making ruinously bad decisions is like saying the government is at fault for a murder because it didn't stop the guy first.
While government regulation of the finance sector has been woefully inadequate, that in no way absolves the finance sector of its irresponsibility and bad judgment.
Finally, as to your second point. Mexico is a 3rd world country and coming from a lower base. Canada's growth is 1-dimensional. Also, those two countries did not have an explicit home ownership policy. Finally, Germany's biggest market, the Eurozone, was roiling in deep recession during that time just as Germany was getting its groove back. So that specific time-frame is bias and, therefore, inadmissible.
You linked to a single year of housing data and tried to make a point. I evaluated it in light of all the OECD data going back seven years, including both sides of the financial crisis and you're going to complain about my timeframe? Give me a break.
You're coming up with excuses for why the data doesn't match your story. What was your basis for your hypothesis other than eyeballing it?
Finally, as to your last point, I disagree. I remember back in Feb or March 2008 when that happened. Some people from the NY Fed came to talk to us. Seeing that BoA was amongst the healthiest and largest bank, and with Countrywide imploding, Feds and Treasury officials talked the people at BoA into doing their patriotic duties by staving off panic with a purchase of that company. But, at this stage, it was simply of whack-a-mole. When one issue was brought under control another popped up. Unfortunately for BoA, when the good people of the Bush Administration left Obama came in and blamed them for everything, which was unfair.
So one of the largest and most powerful corporations in the world was duped into a ruinously bad financial decision by someone saying that it would be patriotic? If our banks are really led by people who are so easily manipulated and so incapable of basic due diligence this seems to be an indictment of the whole industry.
Nobody made BoA sign a contract, but contracts have consequences.
