The point isn't so much that Austrians are wrong, or that they are goldbugs, but rather that they don't learn--and don't value--the past several decades of economic research. The debate's been going on for years, yes, but the self-proclaimed Austrians are making 70 year old arguments against a 70 year old straw man while ignoring any points that have been made over those 70 years.
The debate being doctrinal seem to make the debate seem unimprotant especially when people don't know what it is about. The debate is about how to study the science of economics and the proper use of the scientific method. That's a pretty improtant debate that has been waging on for years.
