RE: Property rights and Basic Income - A viable solution is possible
Theres overwhelming evidence in the study of psychology that the urge to create is universal in all people. Maslows needs hierarchy explains why many people currently live 'parasitical existence'
Some people will have conditions due to personality that render them non-contributers, which is no different than having a physical handicap as a justifiable reason for lack of contribution. This is a minority currently and will remain.
Also, basic income allows for labour being devoted to endeavors which may not have much monetary value, but high value nonethless. Basically, the Arts. (essential luxuries do exist))
Teenagers would pursue much better education on their own than through workforce oriented schooling.
Basic income would make society truly free in expression; the cultivation of the truly Sovereign Individual.
I agree there are many huge benefits to a basic income so long as it is implemented in a way that doesn't result in overconsumption or disproportionate consumption. It must have a natural means of expanding and contracting with the actual productivity of the economy.
Even overconsumption / underconsumption is related an individual's needs (defined by Maslow) not being met. Advertising and consumerism thrive on unhappy/unfulfilled people.
When our needs are met we consume what we need and tend to create more value.
