I owned 1 Gibson since I started playing some years back. Was a Faded Explorer (thus rather budget-ish model). Personally? It was a great guitar. However so was the Dean "Angel of Deth" I owned. Or the Jackson Demmelition. Some of my favorite guitars I've ever owned were Made in Korea.
I'd almost equate it to a placebo effect. Tell someone they're playing a $2,000+ (USD) piece of equipment, they might be more impressed with it JUST because they believe it.
There's confirmation bias as well. Most people hear "Made in China" and expect garbage. Hand someone a guitar with that stamped on the headstock (even if it's a fake stamp and the guitar is really MiK or MiJ), and they're going to subconsciously find faults because of said bias. Same in respect to a Made in the US Gibby or Fender, just the other side of the coin. It won't be the guitar being poorly constructed, it'll be the fault of weather while being shipped, poor setup by an underpaid lazy employee, etc.

The name has notoriety, power, and it sells. I won't say that people shouldn't, because that's up to them. However, for me, 2-3k USD is way too far out of my price range, and I'm not that great a musician, for it to be considered necessary. Fun idea? Hell yeah. Practical? No. Not for me.
