Firstly, the market system itself is regulated, by default. It is the government which agrees to enforce certain contracts but not others; it is the government which agrees with some property claims and not others. This is true of all market systems throughout history. Completely divorcing economics from politics is therefore impossible.
Secondly, I disagree that regulated markets show "less progress" than free markets. 3 places simulatenously had regulated markets in the early 40s - the US, USSR, and Nazi Germany, and all 3 had massive technological advances which fueled things like the space race. Polio vaccines were developed outside the sphere of the market and then distributed largely outside the market sphere, and they led to a lot of human progress, progress that is tough to capture in GDP charts.
