This is such a silly take, you're taking a real observation that people need to decompress but moralizing it rather than trying to understand it. While some activities you would call active can fill the need to destress the majority of them are passive. Creative hobbies are serious work until you're good enough at them you can turn your brain off while doing them. I can do it with programming but it's also my career and I've spent my 10,000 hours getting there. So people turn to reading, listening to music, podcasts, taking a bath, watching movies and TV, exercising, video games, or scrolling through their phones.
Mindlessly consuming content for hours on end is 'silly'. It's easier than doing something worthwhile, sure. Our society wasted a lot of hours doing idle things yet complains we don't have time to be social or get other things done. People aren't lonely, just too lazy to try. Yet they can watch every episode of Below Deck and feel ok with how they have spent their lives...
