Nice analogy. People collect everything. I myself kept every single staple I pulled from paperwork in 2012. Quite a sizeable pile. Put them in a plastic box and display it on my desk.
That being said I'd probably do what you want to do. The way things are any gun might become collectable, might as well have what works for you today and don't worry about tomorrow until it gets here.
