In Ireland, for as long as it has existed with its own government, the two have been pretty heavily intertwined.
The closest thing to an involved government wasn't really in favour of trading in immaterial goods at all. Something close to government intervention did happen in one of the two involved government systems after the bubble popped, but it was effectively unratified and useless (the local equivalent of a supreme court even ruled that the government couldn't interfere with the tulip trade).
The entire thing was just a club of a few hundred relatively rich people throwing themselves at a bubble. Most people didn't have the means or money to participate.
The "mania" name is an insult to those who partook as much as it described the trade bubble. It's not related to the modern psychological definition of "mania" that came much later.
The fact that it's marketed as a story about psychology and mania rather than government policy gone awry is arguably itself a story about psychology and mania.
People have a need to feel like the forces that control them know what they're doing.
