Interesting post. I think about this a lot; since the State is enemy of society and the humane life, a lot of time must be applied to trying to diagnose the consequences of it's existence on the broader perspective of general living. So critiquing the present institutional and philosophical structures that the State incentivizes is important.
If the State was not around and simple freedom was a reality for the masses, the world of ideas would still be an active and healthy pursuit as individuals all have different tastes. More time could be spent on interpreting different types of art, manners, and spirituality. Perhaps new avenues would be explored and there would be numerous of possibilities to dissect.
And without the threat of statist imposition of various ideas, people would feel a lot less threatened by others who want to experiment with them.
