I like all your reason for collecting.

Try being a dealer/seller of Tactical, Survival and Outdoor gear and then see what your house starts to look like. we used to have a spare bedroom that became an office and now it's turned into the gear room/storage room.

I just say to my self "if I'm going to sell trhis stuff to my customers then it's only good customer service to own, test and use the gear I'm selling".

Then again, whatever I have to tell myself to sleep well at night I guess.
