The truth of the matter is that distilling and aging a good scotch or cognac is not that difficult. The difficulty is marketing and popularizing the product. The rarity of a scotch or cognac is a conspiracy of these distillers to limit production of their products to just barely meet demand. With more demand coming from China for scotch and especially cognac, these distillers have to ramp up production, but just barely to the level where they get premium prices but not flood the market. Canada, US France India and Japan produce whiskies in unlimited quantities, but they lack the reputation and prestige of scotch whiskies. Even though produced in the same manner as Scotch whiskies Indian and Japanese whiskies can not be called scotch. In some taste test Japanese whiskies equal or exceed the quality of scotches produced in Scotland.
There is nothing wrong with adjusting a drink to suit your taste no matter how you do it. I was gifted a bottle of Johnny Walker Blue a few years ago. No matter what I did to it I just did not enjoy the smokey / peaty flavor. I added other scotches to modify it and vodka to tame it down but it never suited me. So in the end I butchered a $250+ bottle without satisfactory results. Modifying a drink to suit your taste is not an affectation. Putting cognac in a snifter and requiring three nosings
and a slurping to take in the aromas is an affectation. Refusing Chivas Regal, Ballantine's or Johnny Walker scotch because it is not single malt is an affectation. Drink it the way you like it. It is affectation that causes people to prefer the Rémy Martin X.O. @ $250 or Hennessy X.O. @ $290 merely because the crowd tells them that these are the best, when a A. de Fussigny X.O. @ $150 or a bottle of Jean Fillioux Cep d'Or X.O. @ $123. Lessor known distillers can craft just a high quality a product as the big distilleries.
