Well, I qualify as older. Wiser? Hmm, I managed to lose a little over $200k on tech stocks a few years ago. Learned a big lesson about greed. Also learned the value of diversification. Now... parting out guitars... There is a fellow on ebay who makes a living parting out brand new Fenders. He has been the subject of some discussion on the Fender Discussion Page. I don't know if the market is saturated or not. I pay zero attention to this market. Like our fellow forumite "Straightblues", I buy and sell solely for the fun of it. This is primarily an enthusiast forum. The vast majority of posters here do not have any type of profit agenda. They are here for the thrill and fun of guitar collecting, discussion and the group vibe. Even the retailers who hang here take a low key approach. If you have the time, energy, money, and knowledge, there may be a little money to be made in what you propose. I personally don't think it's worth it.
