Take for example Tesla, everyone knows it’s a little overpriced, but people buy them all the time. If a product offers a very good service, people are ready to buy it irrespective of the price.

You're definitely right about this however how many people have that financial power? Test case, I'm using Nigeria as a developing country where people won't still buy the product even when they know it's quality. Samsung mobile is arguably the best device in Nigeria but people know and they won't still buy it.
