There's a lot of stuff I agree about in there and a lot of stuff I disagree with.
The guitar you buy should be the one that inspires you to play more. If you can afford it and it inspires you to grab it every waking moment, buy that one. You don't have to buy a guitar. These are durable luxury consumer goods. Your level of luxury is just that- yours.
Generally speaking, higher prices (to a certain level) get you better woods (and lighter examples of those woods), better hardware, and better hand-finishing. CNC machines don't care where their located and the nationality of the operator, but price tiers often dictate the quality of the raw materials and time aloted to each unit.
Fender and Gibson (and to a lesser degree, PRS) are legacy brands and their real assets are their heritage. Stickers and logos. The IP ship sailed a long time ago. They still make good instruments, but their upcharge is all about legacy. People will pay more because of the history of the logo, and they will do anything to maintain that status quo. Even their secondary marques have significant brand value that adds to the price.
Every single guitar building company would love to charge what Fender and Gibson charge. The market will not support it. Those that try (even with superior instruments) almost invariably fail. There's a lot of human nature, superstition, tradition, and other stuff tied up in the guitar market that defy logic. It's one of the cool things about the whole experience.
All that said, you don't have to spend a lot to have an exceptional instrument these days. The unplayable $99 guitar of my youth adjusted for inflation would get you an excellent guitar today from any number of brands.
I completely admit I am a complete Fender fan-boy (up to a certain price-point). My tastes have been refined by over four decades of indoctrination and hands-on experience. I have owned and/or played literally thousands of guitars from all sorts of manufacturers, but the ones that stick have mostly been from Fender. I criticize the company often and very rarely buy anything new from them anymore (other than parts), and when I do buy new I avoid paying retail/MAP like it is my religion. I swap parts constantly to adjust for taste and rarely care about "purity". However, this particular legacy brand resonates with me and inspires me to play more. Maybe not better, but more.
Other people are inspired by other brands, models, shapes... I completely respect that. It's all about the right instrument for that particular individual. You don't have to spend a lot, but sometimes that is the best option to get the best result. Not bang-for-your-buck, but simply the best result.
