The claim being responded to was that there is no evidence that "growing with chemicals" has increased crop yields. Evidence was provided that crop yields have increased as the industry has switched to "growing with chemicals." The percentage of those yields ultimately going to livestock is unrelated.
The issue with finding a "happy medium" in one segment of the market is that investment capital will immediately start to flow towards other segments of the market without such constraints.
In your example where TVs are a lifesaving drug, you could argue that we should find a happy medium where TV manufacturers are only making 3-4k in profit. In the short term this would increase the accessibility of TVs, saving lives. In the long term this would cripple future investment in better TVs, reducing lives saved in the future.
Investment is distributed in response to expectation of future returns. If you want more lifesaving drugs you should incentivize their creation, not penalize the field relative to less important pursuits.
Some people will pursue medical research (or invest in it) for its own sake out of an admirable desire to help others. Many more will work for whoever will pay the most, or invest in whatever business has the most potential for profit. You don't have to admire those people, but it's not rational to actively push them away from fields where their work could benefit others.
I don't think such an admission necessarily follows. It has always been possible for determined criminals to invest enough time and caution to make their communications prohibitively expensive to intercept. The vast majority do not do so. Everyone (criminals included!) have to make decisions about the tradeoffs in time, effort, and convenience they're willing to make for security. Changing the default level of security enabled out of the box on commercial devices changes that calculus. It's possible to simultaneously believe that the FBI should not surveil normal citizens all the time, criminals do have the ability to secure their communications to an arbitrary degree if they make the effort, and the default level of security your iPhone provides should be less than "requires nation-state level resources in order to comply with a lawful search warrant."
Ideally we'd see less of "judges rule without interpreting it strictly," which would help garner popular support for future amendments.
