What are the active drivers for one to collect? There are really only 2 IMO:
1 - True appreciation for what you find, the hobbyist (collectors) fits this category, those who want to grow their private collection, maybe trade with friends
2 - Income source for whatever one is trying to fund (drugs, simple income, wealth), "gold diggers" fit this category, those who buy/sell for profit
Lines are blurred in the collector realm by those who trade and more so, those who buy and sell artifacts. Take a look at ebay, craigslist and the more traditional artifact sales websites. News media and the internet in general inform those seeking income via the monetization of artifacts with all the motivation they need. They can quickly search and find that artifacts sell fairly quickly and for decent money in some cases.
Since I have started collecting, the number of people out looking has increased dramatically. The quality of the "newcomers" at least in my area, is questionable. I know there are guys out there with no intention of keeping what they find, they sell everything. I know a guy who has actually got people out looking for him that he pays top dollar for high quality pieces, I find this to be as atrocious as anyone out there looking to fund drug problems or to turn a buck.
The economy and jobs situation in our country right now I think has got people with time on their hands out looking so they can sell what they find and make a few bucks. Once these people start looking, they may never stop even if they get a job, it's an addictive hobby! Ebay should eliminate native american artifact sales since they can not prove whether or not a find is legal or not. Folks willing to pay ridiculous amounts of money for the G10+ artifacts should rethink their obsession, every time something sells for hundreds or thousands of dollars it encourages more people to get out and look for their "lottery" piece.
Discussion forums, it's great to come on here and see what people are finding and hear all the related stories of where, how, when etc.. But the forums too contribute to the increase in laws. As easy as it is for us to find these places, same goes for archeologists, feds, state governments and so on to monitor things as well. While I'd hate to see the forums go away, I'd trade the forums in a heartbeat for the ability to continue to do what I love to do without someone thinking of me as some kind of looter.
Agree with the laws and their reasoning or not - once they are written and enforced, they are here to stay.
Please, no one take offense from anything I've written here, these are my thoughts/opinions only and not meant to attack or demean anyone. Most here anyway, least as far as I believe, are in the #1 category, true collectors.
