I completely disagree.
Until there is a clear intent to convince another that the immitated item is legitimate, no law has been broken and no action can be taken. The underlying theme with forgeries is the criminal and duplicitous aspects of it.
Consider art prints. A print of a lithograph (which is a print itself) can accurately reproduce to the smallest detail every part of the original. It can even include the artist's signature. Yet the print store can still sell it. Why? They state clearly that it's a reproduction, not an original. Yes, they are making a profit from the artist's work, but the work is licensed from the artist (or their estate) giving the shop legal rights to sell them. By your arguments, they're selling forgeries, not reproductions.
The Chinese knockoffs are forgeries because they claim that they are genuine Gibsons. They intend to fool the customer into believing that they are buying a genuine Gibson, when they are not.
So yes, while the definition may be riding along a razor's edge, it is still 100% about intent.
Then we get into fair use laws and usages of copyrighted shapes, logos, etc., which this clearly falls into.... unless he tries to make a profit from it. If he makes it clear that it is a copy, but if he makes a profit from it's sale, it's copyright infringement, not forgery.
