People occasionally need to wind down

Sure, but "find ways to divest from pop culture/find hobbies that are less steeped in pop culture" doesn't mean "no mass media ever". Just like, maybe pick something historically interesting instead of Obama's memoir, or some ursula leguin instead of Orson Scott Card (he was the fascist one right not Herbert?).

And yes capitalism leaves us with less time and energy to get into more rewarding activities, but it also produces treats that are specifically designed to be low-friction and high-dopamine, which makes them highly habit forming if not addictive. Many people feel like they couldn't possibly get into cooking or sports or whatever but then spend hours a day on tiktok or watching TV and justify it as needing to wind down. Its not like leftists are immune to the allure of that stuff but it's worthwhile to strive for a more fulfilling life that is less reliant on capitalism and its treats. People aren't worse for liking the treats, or even for being addicted to them, but engaging in higher-friction hobbies isn't about depriving yourself, it's recognizing that there are more rewarding things to do in life than consoom treats.
