I agree that ditching the whole thing would be ineffective. Even if we did, I would bet that the new system would be the old system with minor differences.

There is good in the system, it needs more people to help managed and identify fraudulent/cheating behavior which is aimed at gaming the system.

I also think we need a smaller net so that fewer things can be patented. Again, this is for the freedom to exchange information and ideas, which leads to the betterment of humanity as a whole.

Everything we do has been built on the ideas and labor of others before us. It makes little sense to me to imagine we will be better off by not letting future generations do the same.
