A love base society removes disease, poverty, hunger, homelessness, war, cartels and most else of what you listed. The world is plentiful. If a handful of humans didn't claim ownership - or more accurately, if we didn't acknowledge their claimed ownership of our planet - life would be abundant and enjoyable for all.
Remove money and remove fear and we are free. All it takes is unison.
I assume your talking about something like the venus project?
One of the many problems with that is who does the crappy work that needs to be done, no one wants to do and robots cant do? Share it? Doesn't work if it's a one off job.
Also there will always be natural leaders in society that will take charge and gain power, intentionally or not. This behaviour is natural and would still happen, this is not influenced by our current society.
How would these people be "artificially suppressed"?
I don't think there is a need to suppress anyone. You're right, there would still be leaders, but the amount of damage one could do in a less centralized society would be reduced, as there would be no, or much fewer structures of power already in place for them to climb.
As for who would clean the toilets, maybe everyone... I don't see that happening anytime soon though, for obvious reasons.
