Yeah but it's like saying "Masterlocks will always be easy to pop off with a hammer". Of course, but by doing so you are actively engaging in fraud, which then puts the onus on you and whoever you are attempting to deceive.
Key phrase. And I'm not saying fraud in the legal liability sense. If you're not trying to hide the fact that something was LLM generated, then you have no reason to remove it. If you are trying to hide it, then there's probably a reason, i.e. you would face consequences for doing so, therefore it is fraud.
