a) be smart enough to get into a very competitive professional school (most people don't have a college degree, which is required, and even objectively bad law schools are somewhat hard to get into),
b) be wealthy enough to pay for it (it costs on average $150k plus opportunity costs),
c) be interested enough in it to actually consider it, and
d) be... stupid enough to actually do it (there are too many lawyers, and less than 1/4 of them say their education was worth it)"
stupid.

And this is exactly why "just go to law school" is a stupid answer in this context.
However, I agree with the guy who called it stupid. Not in calling it stupid, but in that it's an answer that creates more questions than it answers.
You could nuance it and take the steelman version, which is that everyone should be generally educated and know a bit about everything, but we all know it's unrealistic. You can't do part of an actuarial degree so that you understand insurance. But you have to buy insurance. You can't flip through a psychology intro so that you can be prepared when you see a therapist. Or read DS&A so that you can hire a programmer. Or read about structures for when you buy a house, or learn to play the piano so you can enjoy music.
You just can't do all these things to a degree where you are covered everywhere.
Now the problem with certain fields is they reach into everyone's lives to a significant degree. Law is one of those, medicine is another, and finance is yet another.
So you can't even narrow it down to "do these things only", because you can't become an expert in multiple broad fields like that. The only realistic answer is to known a tiny bit about a bunch of things, and a lot about one "thing" and then rely on social institutions to make sure you get what you're due when interacting with experts in other fields.
