Although I understand the point and see it very reasonable, I couldn't care less. If someone wants the PSDs, I'll give them. I've even had this situation: one client asking me to fix a site made by one of those cheap filipinos who (badly) modified the design I originally made for that client. What can you do? I simply laughed and provided my best service as usual and told my client: "see? you had to paid twice!"
However, in such a competitive market, giving LESS than your competition will get you out out the race. Simple as that. And unless you're absolutely the best designer ever, and I mean WITHOUT A SHADOW OF A DOUBT, people will simply say "fuck, I'll get someone else at the same level of quality for the same or LOWER price and get a better and more complete service". As simple as ABC.
Of course, to each his/her own, but for those that are willing to listen to some advise: be smart and provide a better service. Work will come alone.
