I view the general problem with it is simply the existence of other societies.
IE lets say you have 4 societies on an island. 3 of them put all of their focus into developing a sustainable workable long term solution, farming/fishing etc....
1 of them, works on building weapons and attacking the other 3. Result, the murderous colony kills the other 3, then eventually either learns to act like the ones it killed and produce food, or it dies out with nothing left to raid.
Or like say rabbits, if you try and raise rabbits. You drop 2 in the wolf enclosure and see what happens. obviously the result is the rabbits die out. it's not that rabbits aren't a viable evolutionary path. It's that without time and space to grow their numbers before getting encroached by the nearby predators, there's no shot.
Point I'm making is... the biggest problem of developing any system, that works better on the whole. is outside interference. It's the same concept that say modern manufacturing would make smaller and lighter cars better and far more cost efficient. They would be safer except for the fact that they wouldn't survive a collision with an SUV. It's not the smaller lighter car that's the problem. It's the established systems with their flaws are integrated into society.
worth noting, e-mail however was... If I recall ascii porn was among the first things sent.
