I think the key to understanding this proposal is to realize that the state does not have to be a small subgroup of people (or in other words, elite) that it, in effect, is today. State's power is born from the people and as long as it's not centralized in the hands of a small elite who can use it to walk over most everyone else, most of your comments lose their significance.

As for the motivation to take care of the land, why on earth would you be voluntarily paying for it if all it was for you was financial burden?
