I just do not agree with the libertarian mindset. It is a “tragedy of the commons” situation for me. We live in a complex society and share/use the same resources and infrastructure, and the net effect of individual use can be huge. Power grid capacity is a perfect example, where each individual using a bit more energy doesn’t cost them much directly and there is little market pressure one way or the other. The overall effect requires higher infrastructure spending, that everyone pays regardless of if you use a bit more or less energy. Never mind how much pollution comes from energy production, and we all breath the same air. “The market” is absolutely terrible at solving for indirect effects like that.

I also don’t have the time, energy, and knowledge to be an expert on every single thing I buy or use. I know nothing about roofing materials, so having some bare minimum standards and left and right limits balancing societal harm/good and individual choice is perfectly reasonable to me.

Natural resources and infrastructure are a shared resource “owned” by everyone, collectively known as the nation. Protecting that value is what the government should be doing.
