I've been pondering this question lately because if I really wanted to, I could do that. At least when it comes to making videos. Of course, I'm not delusional enough to think that it will be an instant money-maker but if I'd start putting out videos then over time I think I'd eventually get somewhere with it. And I'm not trying to toot my own horn here, really. I'm just conscious about what I'm capable of. I'm a decent writer and I've been doing it for decades now, even professionally. I'm not a novelist but I can put out a decent review or essay. I also know my way around editing and I could even do some design work for those videos since I'm also a sketch artist and know my way around Photoshop (or Gimp for poverty editing). The only thing I'm not really good at is narrating but there are some ways around that too and I have resources.
The one thing that's stopping me, really, is that I don't actually want this to become a job.
I mean, making a video review or essay is a LOT of work. I did a few of those in the past already and it usually required a substantial amount of time. It took weeks of working during afternoons and nights to put everything together and it wasn't even that good because I was just starting out back then. But it was at least enough to make me realize that I don't want to do this on a regular basis because then it sucked away all the fun and passion out of gaming for me and I don't want to turn gaming into work. I have a day job that has nothing to do with gaming, writing, or editing, and I'm perfectly happy developing my skills in all those areas that aren't related to what I enjoy doing in my free time as a hobby, but on the other hand I know that I have something to say about what I'm passionate about and I'd like to put it out there for everyone to see. And I know that simply writing for a blog isn't really enough because I've done that and it never got anywhere because it's just difficult to get people to read shit on the internet these days, or get yourself noticed among the sea of other blogs. At least with videos, you can do something that's more stimulating and easily digestible if you have a halfway decent idea and style.
But again, I look at all those youtubers and streamers, and I started noticing that a lot of them really lost their passion for gaming and became highly cynical about them, or even outright hate them. I don't wanna be that guy.
