I don't mean that in some kind of "mystical" way, but in that other people perceive it to be valuable. For instance, a Picasso painting has very little intrinsic value to me. Given a choice, I wouldn't have one in my house. But the fact that other people are would be willing to pay me thousands (millions?) for it means that it does have value to me (because I can sell it) - but only in the same way that a gold bar or some share certificates do. Whereas the exact same painting by an unknown artist would have no value to me, because I don't want it and I can't sell it.
