The fact that producing stuff is difficult is enough to create an opportunity. If you produce better stuff (price,quality,marketing) you get to sell more and earn more. This gives you an opportunity to invest more in to the system. So you get to be ahead of your competitors. And everybody gets to be ahead as side result with time as well, thus you need to keep investing and keep on trying.
The problem is that some industries feel entitled to retire on mohito island while humanity gets to drag them along.
Also most of people using and developing Linux live off it - one way or another. I'm certain that professional/user ratio is in strong favour of Linux.
Idea that companies put money into R&D solely due to intellectual property, or that they only make enough to put something into R&D because of IP is wrong.
Look at some of the most successful businesses in the world. Selling sugared water, selling grilled pieces of meat, selling washing machines and various appliances, selling pieces of wood that fit together,...
Taking whatever IP from them wouldn't change their R&D and other forward looking spending activities much.
And don't come back to me with low tech/high tech argument. High tech production is even harder, that's why those who know how to do it and keep successfully investing into getting beter, get to run the show. Those who don't know how to improve and those who want to collect tax on everybody forever should just roll over and die.
