I'm talking about long term impact, not emergency measures. Everything you've mentioned is an emergency measure AFAICT.

For comparison, the impact of banning the printing presses only materialised quite a lot later than it happened. Remember that Europe used to be a lot of independent (and feuding) nations, rather than a union of any sort. There were unions of sorts under the Catholic and Orthodox churches, but England for instance was not part of those unions. it was in those times that Europe went through the scientific and industrial revolutions, while the empires I mentioned slowly stagnated.
