> If someone starts copying my likeness, mannerisms, writing style, etc. they could also use that to damage my reputation or harm my relations with other people. I think that those two possibilities represent irreparable harms with no associated business value.

There's 8 billion people on the planet. Unless you're a celebrity, this is not a real problem for you at this point (and if you are, it's a business problem).

There's no way for a large model learning on the entirety of the Internet to somehow convert "copying likeness, mannerisms, writing style, etc." into damaging your reputation; doing that is something hyper-targeted, and at this point (and in conceivable future), there's no middle ground between "plausible deniability" and "someone targeting you specifically, which they could do just as well in pre-AI times".

You're also not as unique as you think. There are many people with same mannerism, many people with same writing style, etc. Nor are those things constant over time.

The flip side of not being a unique snowflake is also that anyone's contributions to the public Internet are, for purposes of AI training, worth approximately $0 on the margin, and impact the model just as much. It's in the volume of data that the patterns emerge that LLMs learn, volume too big for any person to be entitled to a meaningful part of it.

You could also make the same argument about check forgery or wire fraud. "If someone passes a bad check in your name it's not a big deal because you're only one of 8 billion." However when it happens to you, specifically, it's a big deal because you have to fight the bank and the merchant over it.

"You're not special" is a bad argument for why someone impersonating you isn't a problem. I mean even Black Mirror explained why impersonation is a problem in the very first episode many years ago. You don't even have to be a celebrity, you only have to be in someone else's way.
