I agree with most of what you finished with, but strongly disagree here. Scarsity, artifical or natural drives a need for resource distribution which then gives rise to a greedy profit motive.

The internet and computers in general have largely shown that when resources are plentiful people will create for the shear desire to create. So much of the internet, and modern technology runs off software and hardware designed for free, or at extremely low cost.

Linux, OpenSSL, heck Open anything, all built because people were dissatisfied with the existing commercial available model, or just wanted to create something new.

Going beyond software the amount of free entertainment on the internet is staggering. Much of it created without seeking to use it primarily or even at all as a means of income.
