For the wreck types I listed, I object to divers taking objects because it is either outright illegal as international law still recognizes legal ownership by a current entity (person, company or country), or it has significant value in being studied, and it is/will be studied. Sites of mass death tragedies are sensitive issues to people and I learned early in my life that it usually is not worth the hassle of messing with other people's "sacred graveyard" sites. Perhaps one too many trips to the movie theater to watch Poltergeist.
For the rest of the wrecks, it's just a supply/demand argument. Within my diving ability, there is a limited number of "good" (ie interesting) wrecks. Unfortunately, the range of my diving ability is over-populated with other divers who also go to wrecks. If I remove items, and they do as well, the consumption of these limited reasources will decrease the supply of interesting wrecks far faster than it is replaced by new wrecks. Pretty soon, if everyone strips the items, then there will be no wrecks worth diving to.
By my leaving the items to slowly degrade into rust will unfortunately reduce my personal interaction with the wreck, but will allow others to have at least a shot of experiencing something. I try to make up the lack of "physical" momentoes by underwater photography, and hopefully underwater filmography one day.
Non-culturally/historically significant wrecks who are abandoned "fair game" to divers. For example, a fishing boat that goes down during a storm and no salvage operation planned is fair game IMHO. It has no significant historic/cultural value, no issues of legal ownership or legal salvage rights assigned to anyone. While I personally will follow my own code of conduct at the dive and not remove anything, it wouldn't upset me very much or at all if others removed items.
Ships and other non-purpouse-built-reef-creation items sunken for artificial reefs are not wrecks, they simply are hunks of metal abandoned on the ocean floor to create good PR for participants that was of greater value than the scrap costs they would have received by dis-assembling the item.
