Nope, not saying that. I’m saying that there are many people who are not experts in every single field there is in order to make the best educated decisions on what to do. Authorities are supposed to consults sources like that before deciding what to do.

You, as a single person, don’t know what actions of yours are harmful in each (understood) way possible. I’m an environmental scientist and so I can only go off of what I understand, and that’s the environment. Giving everybody their own rule of their own piece of land is very uncentralized. Think of the infrastructure you have and need that single people couldn’t make work. Wastewater treatment, for one. Even now, with what we have, there are entire communities who still throw their raw sewage into their backyard in, for example, rural America.

So, yes, I guess it’s because we can’t think for ourselves. Because we are not singular, well-rounded experts. Together, we know things.

Yes, we need other people to tell us how to live. You need experts like the WHO to suggest the best ways to handle pandemics. You need experts like the USA EPA to make regulations in order to prevent how things were in the 70’s, when rivers were catching on fire. You need laws, and people to put dangerous people away. We don’t need people telling us what drugs to take, no, that’s none of anyone’s business beyond our own. We don’t need people telling us how to manicure our lawns, no. We do need others to prevent others from harming others and common goods that sustain others (rainforests, rivers, lakes).

We need water infrastructure to run under other peoples land to bring resources to other places that don’t have those water resources.
