I'm not saying that emotional damage isn't very real and devastating, but it's certainly not something on which our courts should base their outcomes. It's too subjective, not provable, and very difficult to quantify.
You get a jury together and they decide. You (and Alex Jones) may not like it, but it's a well established system at this point.
I am not a lawyer, but I suspect if you asked one about your plan to go on YouTube and insult people, they'd advise against it. For one thing, YouTube might see it as a violation of their terms of service, and for another thing, you might be opening yourself up to litigation, which even if you won, could still be expensive.
