Multiple companies have turned into glorified financial firms with their core product becoming auxillary. Look at airline credit cards, Starbucks loyalty cards, Block's Bitcoin repository, AMZN investing in Rivian and so on.
We glorify operators who keep operating - such as Elon, Zuck, and Bezos - but, few people seem to do it.
Long live the operators.
The Starbucks business remains almost entirely their retail service business.
In a way, the cheap bulk goods are just a way to convince people to get the membership.
Though you could make this argument for gyms, which are notorious for selling a lot of memberships to people who lack/lose the motivation to use them.
