So, a 1956 Ford Thunderbird in original, but faded paint, should be repainted?
Value is what it is, and if guys who know the value of an item in original condition compared to refinished condition caution or warn (or, heck, bemoan) the waste of refinishing and the loss of value that comes with it, they get trashed.
There is another side of that coin. Those who call them merely tools but then get their panties in a wad if there is a scratch and suddenly need to refinish them seem to place too much emphasis on that consumable. Me? I haven't refinished a toaster, TV, couch, or the like in my life. But, I do know quality, and a refinished plantation desk has much less value than one that has not been refinished. An 1876 Morgan dollar has more value unpolished than one that has been polished. An 1814 Curassier's sword is worth more with cracked grips and tarnished basket than one "refinished."
And the idea that I should buy a gun to throw away is also silly. Yeah, I do expect my firearms to last a long time - which is to say out live me. We take care of our stuff that way. They aren't a bic lighter. I throw my used up pens away. I also don't worry if they get nicked up.
I also know that a well-worn firearm bought, then refinished, means I could have gotten a better one. Why waste the money on inferior since I'm going to spend the money any way? Why buy a 1961 Impala only to drop another ten grand into having it purdied up when I could go ahead and buy a better one? The better one will cost the same and retain its value. I also don't wipe my butt with $5 bills.
But, I do believe in private property. If I give you a $5 Confederate bill from 1862, it's yours to burn to light your cigar. I may still call that unwise, I might even bemoan the needless destruction of the $5 bill, but it was yours to destroy. So, this isn't destruction we discuss? Okay, I might give you a tarnished 1840 Wrist Breaker. You can polish the guard and blade until it shines. It's yours. I won't say its a good idea. You want to use it as a machete? Fine by me. But, don't get too upset when I point out you are wasting money and losing value.
I find it odd, though, that many of the guys here to proclaim they are mere tools get so upset about weapons buy-back programs. If such a program makes a leftist or anti-gunner happy (the theme of the day at the present it seems), why would we care if they "take guns off the streets." The seller is happy, the anti-gunner is happy. Everyone is happy. Why would we care if they crush a ton of revolver, rifles, and gear with a steam roller? The guns are theirs to do with as they please. Makes mine worth more, right?
