Absolutely.
The only problem is that while we consider these concepts with nuances, governments have vested interests in promoting an ideological case for why limited freedom is desirable. And they have in mind a very different set of restraints than we do.
One example of positive restraints are free market commissions. Most of the exceptional art in history was funded via commissions, where the commissioner was a kind of co-creator or producer in more modern terms, hiring artists and musicians for grand scale projects that would take years to finish.
That is the kind of boundary-breaking restraint and incentive structure that push creatives beyond their comfortability horizon.
A restraint that helps us to break boundaries and push through new grounds is possibly not a restraint technically but perhaps more of a voluntary calling, a journey challenging a mountain of our choice. We will forever need mountains to climb.
