why I don't collect vintage Rolex

I was perusing the net and stumbled upon this article (could be old news)

Arguing about vintage vs new aside, I think his logic is flawed in that if you are collecting, don't you want to collect something that is in demand? If you spend 30K on a DRSD, which is the grail for many, don't you think it will only go up in price or at least retain its value since there are only that many around and most likely supply will lessen as time goes by? I mean if someone is willing to pay 30K today, there is a high possibility someone is willing to pay 40k down the line, don't you think? Its like saying I don't want to buy a van gogh because its over price.
