Chewing up the finish with a belt buckle is downright careless, IMO, and easily avoided, but it all depends on your priorities. I derive satisfaction from playing and admiring the aesthetics of a fine handmade instrument. There's absolutely no reason to be sloppy or disrespectful just because I'm standing on a stage, however crowded it may be. A little common sense (no paranoia or panic required, thank you), an awareness of the playing environment, and good technique have kept my instruments damage-free for decades, and they deserve nothing less.
Sure, instruments are tools, but I don't pound nails with a fragile, delicately-finished musical instrument, and I don't play music on a hammer, so it stands to reason that I'd bestow the appropriate amount of care on each depending on its intended purpose.
Yet another remarkable quality of Fenders and their clones is that they aren't fragile: they can take heavy belt buckle rash without falling apart at the glue joints.
Seriously, if you want to care about meaningless scuffs, be my guest. I won't argue that they can affect resale value. But let's not get silly and say that cosmetic imperfections are a sign of sloppiness and disrespect. If I don't care about the possible drop in resale value, and am not nitpicky about aesthetics, then there's absolutely no reason for me to avoid belt buckle rash: it may hurt your eyes, but it doesn't hurt the instrument in the slightest.
