The whole notion of recreating living persons the way he did, down to a few percentage points of discrepancy, should be illegal
...But if enforcing a law is incredibly futile to start with, what's the point? Writing down the law will just erode respect of law in general, then.
Holodecks as a whole clearly aren't considered objectionable, and their very purpose is to imitate life to a pleasant degree. It thus doesn't appear to be a majority sentiment that spitting images of real people are a bad thing. It may be creepy for the victims (we see Riker, Troi and later Kira react adversely) - but apparently it's another of those things where the perpetrators outnumber the victims sufficiently to democratically define the thing as right rather than wrong.

Yeah, & I concede that it is a highly debatable point, but Geordi didn't just recreate the image of a person. He compiled data on her, her personnel file, her behavior, memoirs, lectures, etc...
He created a duplicate of her, so he could access her mind, & benefit from her way of thinking. Surely it's forgivable in his case as it's a necessity for their survival
But the practice in general would have to be condemnable, because it's kind of akin to identity theft, or theft of intellectual property. If someone of lesser scruples could do this, then they could use it to sort of steal their ideas or gain insight into how someone might create something. It could be crippling to a design engineer
Take Noonien Soong, for example. If someone compiled all the data, & personality on him to recreate him in a similar manner, then a holographic duplication of him could be created, & given a broad spectrum of parameters, like the Voyager EMH
Doing so might highly further the cybernetics research he was conducting before he died, which is probably a good idea for someone like Bruce Maddox, but if you were doing it while the person was still alive & active & in Soong's case working privately, & secretly, you'd be using the technology to try to steal trade secrets as such, because you've duplicated the mind of a person, within a few percentage points of what they are really like
