The advantage is simply being in a place where you can focus on creating something like a podcast that will not make you (actually will cost you) money for a good long while.
Most people without money or support don't have the time and resources to devote to creating something like that.
Human beings need a little bit of downtime for general decompression and whatnot in my experience (unless you want to go for that coveted 35yo burnout status). I'm not saying that that 2-3 hours of tv/social media can't be more efficiently spent on a different form of relaxation plus some kind of after-work job/hobby, but I do think it's oversimplifying a bit to say that leisure activities = waste.
