It doesn't cost more money to cook food well... the time it takes is by and large the same, until the preparation and the processes you introduce start to take over the reason why you are doing it. The visual presentation is the principle driving force behind 'signature' Michelin restaurants, providing an excuse to charge ridiculous amounts for very small portions as a 'dining experience'. Generating TV celebrity status is then a driving force behind the branding. It's all getting more and more extreme and, frankly, silly.
You obviously know little, and understand less, about what Fine Dining is all about.
I was going to go on and explain why and how you are wrong - but I strongly suspect I would be wasting my time.
By way of analogy:
A bike is a bike is a bike, why do amatuer cyclists, like some on here, spend extreme and frankly silly amounts of money on bikes to the point that the kit you are riding takes over from the reason you are doing it?
The visual presentation of a bike or clothing is the driving force behind 'signiture' cycling kit - providing an excuse to charge ridiculous amounts of money for cycling kit.
Professionals benefit from the milliseconds difference in shifting speed on of a top range group set or electronic shifting - an amateur with that level of kit is just pretentious nonsense.

Four walls and a roof make a house - why spend money on good design?
