My biggest concern by far would be losing my job and being made unemployable, thus ending up homeless.
And that's the biggest concern for most people when it come to doxxing. It's very unlikely that someone is going to show up to your apartment/house to do something. You might get some harassing phone calls and pizzas sent to your house, but the trolls doing this would get bored pretty quickly. But the big thing is, if there is anything negative about you on the internet, it's a near death sentence for your career. This doesn't effect e-celebrities when they get doxxed since they're effectively self-employed and work online, but if you're just a regular guy with a regular job, getting doxxed can very easily ruin your life beyond repair. People have killed themselves over this.
Companies are extremely conscious about their brand reputation, and no company wants a reputation of hiring incels. We're possibly the most hated group that exists right now. And HR departments and 3rd party companies that do background checks are pretty thorough. If there's negative info about you publicly on the internet and it's attached to your legal name, they're going to find it, and your application will be quickly thrown into the garbage. From their perspective, they have dozens, possibly hundreds of qualified applicants, so why take a risk with anyone even if the risk is small?
This is why what little social media I have that's under my real name with my real pics (not having ANY social media with your name and real photos is considered a red flag) is very bare bones and milquetoast.
I would feel sad
