Care to explain how this type of society will motivate it's people to expend energy and time to benifit it?
I mean, why would anyone want to be an advanced engineer if there is no benefit for them?
Why a lot of engineers and computer programmers is involved in plenty of open source project if there is no benefit from it.
Why there is plenty of people around the globe that works for free by for example helping poor people in 3rd world countries.
Would you like to spend your life just lying around and doing nothing instead of doing something meaningful. Me defiantly not.
"A lot" and "plenty" is not very specific. Do you have any estimates on how many computer/network systems out there run open source software/hardware versus paid for (like Microsoft or paid-for Linux systems)? Or how many engineers have invented things and provided their inventions for everyone for free instead of going through the trouble of patenting and selling their invention? Inwould guess that despite there being "plenty" of those, the percentage compared to the overall number is really small. I know my grandfather did not use his few post-doctorate and doctorate degrees, and spend ten years of his life working hard to invent something, just to give his invention away, no matter how much he enjoyed working on his project (part of it was him enjoying it, part of it was to leave a legacy, and a big part was to help make our whole family financially wealthy).
Also, you are only mentioning services here. How many examples of free products do you know of? Are there any free cars, free phones, free computers, free furniture, or something similar out there, provided by generous labor of workers who made them without asking for any compensation for their work or materials?
