The point couldn't be better made than how you've put it. The truth is that many people are creative without their even realising it. They make it worse when they become addicted to the ever-present distractions called TV, internet, social media, et al. It couldn't be better summed up than the way you expressed it: 'When we spend the majority of our time being entertained by the creations of others, we slowly lose the ability to be creative ourselves.'

The five reasons you gave for people's inability to generate good content are instructive. The key takeaway advise here is practice, practice, practice. The only way to be a champion is to practice.

I love the simple yet far-reaching admonition that if you want to become more creative, spend time creating. Keep searching until you find that which is lurking inside of you. Finding is for those who search, not for those who complain, who sit back and do nothing.

The cap of it all is your very last, winning sentence. Thematically instructive, idiomatically entertaining, and stylistically relevant are the words: 'The well is only limited by how deep you are willing to dive.' WOW!!!

Thanks, @tarazkp.
