As for their being a maximum amount, this is largely just a book-keeping measure. As it is unlikely that many citizens will even be able to consume this much, it is unlikely to be much of an issue.
If I'm misconstruing the above in any way, please forgive me. But, if there is no maximum amount or limit to consumption, is it not plausible that greed would essentially 'take over'? I don't mean this in an end-of-society sense, nor am I making this a moral issue. What I mean is that it is somewhat a characteristic of humanity in general to just keep on taking, until you can take no more (ie overgrazing, deforestation, etc). Thus, would it not be conceivable that people would begin to just keep taking out of a wish to acquire more and more of whatever it is they desire?
I don't really like this example, but isn't it kind of like leaving a child unattended in a candy store? They see all the sweets around them and gorge out until they become sick (in most cases, unless the kid has just emerged from McDonald's or something
). Wouldn't people in essence be able to do the same?
Again, if I have misconstrued this in any way, I apologize. I'm kinda new to the idea of technocracy, though I truly do find it intriguing.
