I mean, if that's how we're going to talk to each other, I can engage on your level...

You are soooo right! There's no such thing as a network effect or a first mover advantage! If something exists and is self sustaining (my original point), therefore creating that thing is trivial and anyone can do it (your invaluble contribution)! Your logic is flawless. Have you considered going into freelance consulting? Someone with such good and original ideas should be charging money for them.

There's definitely some very large critical mass necessary for the network effects to kick in. Is that mass such that there can only be one? Or could there be three or four, like other social media? Arguably Instagram is as large a video platform, though obviously very different. Same with tiktok; the individual videos might be shorter but the bandwidth costs scale with watch time.

you don't need youtube scale - but you need to be a lot bigger than most others are. You need to be big enough that ads pay for a full time ad salesperson as well as your other overhead.
