I don't know if anyone will "concede your point" because your point does not make much sense. Stolen photos are the bright, flashing neon arrows pointing toward the scammer.
And no...not all use of stolen photos on the 'Net equals a scam (in the monetary sense)...some people just like to make themselves look better by having fancy photos on their websites (whether it's snakes or scenery or whatever)....and rather than go to the trouble of taking them themselves, or paying for them, or even just asking for permission....they think it's fine to take someone else's work and use it however they want. They may not be out to make money with the stolen photos, but it's still wrong and shows a distinct lack of integrity and character in the person who would knowingly do it.
