Lloyd, I took the title to mean that if your environment changed, whether economic, or social, what could you do without. I'm never sure where William is heading with a thread until half way thru. If either of the changes I mentioned here were to occur, then maintenance, and security, problems could, and most likely WOULD occur.
As I have gotten older, I have become more interested in what I can reasonably USE, as opposed to what I want. As a result of my thinking changing with age, I WANT less, and look at the more practical side of possession regarding firearms, and other things.
Another example was when the 2010 Chevy Silverados came out I told my wife I was gonna go get me one. I did, and almost 4 years later, it had barely 9,000 miles on it. It would sit in the carport for a month at a time without being driven. It made no sense, so I sold it. I also like guitars, but I only have three, and two are endanger of new homes, as I play mostly acoustic. My son, and a couple of friends want me to exchange my Vulcan 1600 Classic for a Harley, but the quality for the money makes no sense.
I have taught my children all their lives, that money and possessions are not signs of success in life, as I have never seen an armored car in a funeral possession, or a luggage rack on a hearse. I will take a good rep over money, and possessions any time.
HOWEVER. If owning a lot of guns, collecting guns, or butterflies for that matter is your hobby, then by all means, get out the gun oil, or the net. I don't condemn it, I just grew away from it myself. Sorry for the confusion.
