Just so you know, plenty of people have been penalized for practicing law without a license. If someone engages in insider trading based on a mistake you made on the internet, you can be liable. In my jurisdiction, that would involve me taking money (not just talking on the internet), so I'm not at risk, but in plenty of states, you can be. A lot of this hinges on the difference between "legal information" (which is generic) and "legal advice" (which is specific). There are whole law review articles on this, which I read more than a decade ago, nerding on something related. But that's beside the point. A major reason for the disclaimer is that people SHOULD be aware of my level of expertise. I do the same on technical posts too. I'll disclaim whether e.g. I have world-class expertise in a topic, worked in an adjacent domain, or read a blog post somewhere (and wish others did too). It's helpful to know people's backgrounds. I am NOT a lawyer specializing in securities law. I know enough to tell people the line is more complex than trading on non-public information, but I am utterly unqualified to tell people where that line is. If you're planning to do that, you SHOULD NOT rely on it. Either read relevant case law, talk to a genuine lawyer who specializes in this stuff, or find some other way to educate yourself on whether what you're doing is okay. So it does matter I'm not a lawyer, if not for the reasons you mentioned.
