Can you bring up some good examples of that? We've got the mentioned loudness war, patent trolls, insurance companies with race to the bottom, people destroying the earth right now and who will keep ignoring global warming where it's profitable, antibiotic resistance via over-prescription, internet buffer bloat, software size bloat, etc.

I love the idealistic view of the sane economy, but no, that's so not how markets work at the moment. Especially in this case - how exactly would any non-war-mongering company stay in business if the name of the game is "how wide/loud can you transmit"? It's not that companies are sabotaging each other. It's that if companies can make a better product on an unregulated RF market, they will. This will most likely get into someone else's way and those in turn will have to upgrade as well. There's only constant improvement on both sides.

If you're able to find any, you can compare the output spectrum from any RF toy that's FCC registered and one that's not. Guess which one bleeds noise on a wider spectrum around it's intended frequency.
