Well, to begin with, both the watcher and the creator are clients of the platform. Both sides feel bound to it, even if both dislike it.
Then, YouTube premium is literally 20 machine coffees a month in my first world country. 15 if they're done by someone. You seem to be speaking "privileged minority".
What you are trying to point is that in the United States of America (and maybe Canada) you people have coffee that's so expensive that two of them pay for YT premium. You're only missing out on most of the internet (eg. Not the US).
Starbucks is notoriously expensive and nobody refers to it as coffee round here. Starbucks in my first world country is considered something for hipster digital nomads. You can't find them outside areas with tourists as everyone else is happy with "regular" coffee that's literally 10 times cheaper.
Saying that two coffees equate to YouTube premium while using Starbucks as a metric is like saying that a car only costs a watch or two while using a Rolex as the reference watch. If you consider a Rolex to be your reference watch, cool, you're a privileged minority.
