I completely follow your arguments on the lack of crime on a Technate, but that in itself is only half of the issue I was refering to...
WRT:
The first one I will mention is the non-transferability of energy-credits as opposed to money. By using a device similar to today's debit cards, no one could beat you up and steal your money. Even the weak PIN security system, which still works far better than money does, could be supplanted by some sort of quick and easy biometric security, such as finger or voice prints. Not flawless, true, but still prevents 99.9+% of potential cases.
Since you've not seen
Minority Report, the system used in the film is one of retenal scanning, but the technology is advanced enough the the scanners can be placed up on walls and can read people's eyes from many metres away. This relates to the energy credits...
For example, if one were to use a public vehicle for transport, then the car would have a scanner in it, and would read a persons iris automatically so that the user does not have to
do anything for the credits to be charged to them. But for these "biometric security" systems to work requires a
database. That in intself is the "Big Brother" thing I was talking about. The automatic systems of the technate cannot work without the 'state' knowing everything about a person - which is then open to abuse by those who are administering the system. I don't like Joe Blogs so I'm going to "delete" him or whatever.
You see where I'm coming from? That's the kind of thing that a lot of people will find very hard to accept, because it means trusting ones entire existance to a machine
system.
And while I remember, I have just though of another point. Consider this possibility...
That technocracy is not in fact a removal of scarity by elimination of the price system, but is in fact a deferal of scarcity to a different point in the productive process. Machines make everything, but machines require enerrgy to run, and energy is a scarce resource. Therefore people need credits as a way of "rationing" energy. So, in that regard not much has changed and there is still some basis for conflict.
All the above considered, I'm not saying that technocracy can't work - indeed I rather like the idea. Just that like all systems, it does have certain 'issues'.
