I think only partially, Roddenberry's point was we had evolved passed needing money and fighting over personal beliefs.
Hippies never were interested in exploring space though, having serious weaponry just in case and of course I didn't see too many Federation types getting stoned and tuning out.
We still had to deal with other alien races that were war like so it wasn't the hippie utopia reality out there in the galaxy, Trek found both friend and foe out there.
