As virtua already said your comparison is lagging. I'll use my new triathlon road bike as an example, which replaced a 20 year old model. The new bike offers some features that were not available back then: oil pressure brakes, a multi-adjustable stem/handlebars, electronic shifting, a drinking bottle integrated into the frame.Any snake oil implies not at all such improvements that are measurable.
You bought a trendy camping kit, yes, it is very beautiful and weighs a kilo less, but you have not become a more experienced hiker from this. But you feel like a steep hiker.
Did you buy a 4kg bike for the price of a car? But you didn't win the Tour de France. But how do you feel on this beautiful bike!
At least the brakes are a safety factor too, the rest adds to comfort. With hifi snake oil however. It only takes money out of your pocket. At least for me, as I am not a "believer" and want my audio gear to perform without being flashy.
