But oysters are really not good. It tastes weird with too strong a note of salty water and has a pretty bad texture that makes masticating unenjoyable. They are poor man's food that got super expensive with clever marketing and supply management (and since they need to be alive the supply chain is extremely complicated and expensive, you can't store them for long).
If you live near a sea and can get them dirt cheap why not, but if you live far into the land, they are mostly a waste of good money and a way for pretentious people to appear fancy/rich at the Christmas holiday.
There are lots of ways to cook oysters, which significantly lessens the briny taste and gelatinous texture.
While it's true that their rise in the West was mostly from clever marketing, oysters are just considered normal seafood in many countries and are cooked into dishes.
But yes, the premium price due to the raw oyster trend makes it not worth it if you live far away from the sea.
