As for not wanting to share places, well thats part of the Overlanding we all want to go and see beautiful places too but don't forget that part of the fun is going out, seeking and "discovering it". I hunt and fish, so I understand (or maybe I'm just used to it) people not wanting to share their "Honeyhole" so I don't dare ask where that is, unless the person showing it volunteers the info, then I will ask, politely. I can respect a persons silence; sometimes it is justified. For the most part people don't want to share it because they don't want that little slice of heaven to become a county playground for everyone and just get ruined, unfortunately I've witnessed that.
As far as equipment selling for high prices, yea I see it. Those prices seem elitist but if someone is able to pay for the asking price, who am I to say no, don't do it. If you like a product buy it, if you can't afford it but still want it, save up for it. If you still want that product but can't or don't want to spend the money then make it yourself, maybe you will see a justification for the cost, maybe you have the skills to do it, maybe you can even make it better. Or maybe just get the satisfaction of making something with your own hands and get the feeling of accomplishment for making something with our own hands and skill. We want a lot of things, when we see all these nice new products we are like kids in a toy store. Somebody had to come up with it, develop and market it. But I have also seen things that make you go "Thats crazy! I can make that and save $XXX". This is also an often overlooked perk of Overlanding, making it yourself! DIY!!! Part of the adventure is prepping for it.
