So the harm is that some massive VCs with billions of dollars to spend on their investments, might be a bit more confused about what someone else's "real" valuation is?
They are qualified investors. I think they can do the work on their own to correct it to the "real" valuation.
I am not sure what is confusing about this. If a company is too expensive, the qualified investors who are spending their investment dollars are free to not buy equity in those too expensive companies.
They manage billions of dollars! I am sure they can figure out how much a company is actually valued! They aren't going to be "tricked" by some valuation scheme that randos are pointing out in HN comments.
