and thats a perfectly reasonable stance. you're a shooter, you want a gun to use it, not to collect it. but some people do buy things to collect, be it for an investment, or just the enjoyment of owning something that is rare, historically significant, or just cool to them.
i personally would have no interest in an albanian sks, a russian one works just fine to shoot and i don't even bother shooting that. but that doesn't mean that the albanian sks is not a very valuable sks on the collectors market and worth a lot to people who collect uncommon sks.
i also have no interest in high end sports car, huge mansions, $10,000 custom built guitars, vacations in the carribean, going to concerts, going to sporting events, travelling the world, breeding snakes, opening a bed and breakfast, deep sea fishing, scuba diving, yoga, eating contests, watching netflix, bow hunting, watching the olympics, baja racing, collecting baseball cards, learning to speak spanish, home brewing beer, buying bitcoin, going to a casino, building model airplanes, or spending $12k on a long range precision rifle when the farthest range i have is 300 yards.
but that doesn't mean that people who do enjoy those things are insane, stupid, or wrong, they just have different interests and choose to spend their money in different ways.
i would rather spend 5k on 2o r 3 guns i could shoot often, other guys would rather spend 5k on one rare example of some carbine from the civil war that they will never shoot and only study and look at. that's fine by me, no criticism here.
