I've thought about this myself -- getting into the youtube video business -- and let's face it, you can't really eliminate the possibility until you're dead, in a nursing home, the world collapses, or something like that.
I think the biggest challenge for you, Sean, and maybe me, would be the PRODUCTION of the videos. Editing them. It takes time, depending on how "perfect" or "polished" you're shooting for with your podcast and/or video.
Personally, I don't like shows that are TOO polished -- I like a bit of down-to-earth, within my reach kind of thing. Nevertheless, the number one rule of videos is the audio has to be good. If the audio stinks, it doesn't matter how good the moving pictures are. So you at least need a good microphone.
My recommendation would be: scratch the itch. Give it a try. Create a pilot episode at least. See how it goes. Now it's true that for something to succeed you really have to pour yourself into it and promote it. Some time I'd like to start a thread on "success" especially for middle-aged men*. So you want to set some realistic expectations for the first few test episodes. It's a new channel with 3 videos. But if there's ANY measure of success/interest, you should be able to extrapolate that, assuming a steady commitment to your channel.
Anything involves risk, so if you're really interested in this maybe it's worth the risk of some of your time, to see how it goes. You won't be risking much, if you just record 1-3 episodes. Then you can upload them different places, and REALLY EXPLORE monetization options. I just heard today that Odysee is going to start doing advertising. They already have some kind of crypto you can earn. EEVblog said he makes almost as much per user on Odysee vs Youtube -- though MAYBE he got some special deal, since he's one of the biggest guys on Odysee (because he had so many subscribers -- an established channel -- on Youtube)
I can tell you right now, you will end up with a finished, edited MP3 (podcast) or MP4 (video) which can be uploaded to any site. It's not like you have to re-record for each distribution channel. Those self contained "masters" can be archived and they're yours forever. It doesn't matter if EVERYONE shut you down. You'd still have all your videos/recordings.
But to really test out and explore the various options, you'd need some content. Both the content and the "exploration" of what to do with it (how to get it to the public's eyeballs, how to distribute it), would involve some small risk, but the cost would be 90% time. You might already have a microphone and smartphone that can record decent video. Maybe a $25 tripod from Amazon, and some lighting, and you'd be good enough in the equipment realm. If you're doing an outdoors video, you don't really need artificial lighting. But a microphone is a must (you don't want the wind muffling your voice. Have you ever heard a windy-noisy youtube video? Those get skipped.)
More advice: don't spend hundreds or thousands on equipment till you make your 10th episode and you commit to the whole endeavor. A smartphone can do very good HD video, with an external microphone. Yes, you need to get an external microphone, maybe even wireless lavalier microphone. Spend maybe $200 tops. But don't go for the real nice mics until you can justify the cost. Just get yourself to 80% of perfect which will only cost a few hundred -- don't spend those thou$ands$ to get the last 20%. Unless you can think of other use(s) for a high end microphone. It all depends on your financial situation of course.
* When it comes to successful endeavors, or "finished projects", I've only had two really: chantcd.com and CathInfo -- both took many hundreds of hours of effort, over many years, for them to "succeed". And in 2013 I did successfully write a complex Android game, followed up with a second game a year later. But what bothers me is that I haven't had any successful projects, websites, or endeavors in years. Maybe you can only "have" so many, unless you can hand the old ones off to a management firm? I don't know. Am I at my limit for what I can handle? Webserver, CathInfo, chapel, 5 acres, 9 kids? Perhaps.
