Lol that's like saying you can make a career out of your love of playing and releasing music. Sure, get to the end of the line. Or playing games and streaming it. Yes, a few make money that way. But theres a vast vast oversupply of people who would want to do that. You have to be very good, work hard, and be very lucky in addition.

Right so if you're not very good at then pick a different career and quit whining.

Running a YouTube channel is not a viable way to make a living unless you have an existing audience or get blessed by the algorithm. There is an oversupply of people making video content, and only a small portion of them succeed. Plus you are at the mercy of YouTube’s frequently changing ad revenue terms (the “Ad-pocaplyse”) and opaque demonetization/takedown rules.

Trying to become a tenured professor in the humanities isn't a viable way to make a living for most of those people either. Only a small portion of them succeed. Plus you are at the mercy of the faculty committee's frequently changing selection criteria.

Find a patron who finances it, as it always was. There never was a society that would fund everyone full time just for having neat fun chats.

Alternatively take up a day job like everyone else and join a philosophy / arts / book club as a hobby.

We have more access than ever to the materials.

"There never was a society that would fund everyone full time just for having neat fun chats."

That was not the request, nor claim.
