Cops would never expect you to try to escape on foot, it’s perfect
This has some ideas: Crowd Funding - A way to exploit the well-meaning and gullible. I think it was meant as a cautionary tale, but one gets ones business ideas where one can. Would I have to set up a bank account in the Caymans in person or can I do it online?
Advertisements.
Same way Facebook makes money.
Nope, we’re saying there will need to be some effort and/or expense. To make even a basic video you’ll need a camera, some lights, some video software and a place to record, for instance. As far as content, it can be almost anything. There are people that simply record themselves watching other videos (k-pop, comedy specials, etc). Unbox Therapy has 10M subscribers and he records himself unboxing phones and computers; he’s got a killer studio set-up now, but that started with a camera, a table, and a new phone from Best Buy or something. BreadFaceBlog is a young woman who mashes her face into varieties of bread. Heck, in Asia people make money recording themselves eating (mukbang videos).
Like I said, effort. 
You can start with whatever you have. A decent smartphone camera can easily be good enough - lights and a studio aren’t always necessary (for example if your content is recorded on the street or out in the woods, or just during daylight hours in your kitchen) and there is some very good free, professional-quality video editing software available.
Would it be possible to sell advertising in your videos yourself or to put sponsored links in your video description, or would this violate Youtube rules?
Apparently sponsors are fine if you notify viewers that the video is sponsored. The thing is that sponsors don’t show up until you’re racking up millions of views per video. No one’s going to sponsor a newbie like dropzone.
I don’t know if there is a rule, but if there is, then no one is enforcing it. Look at any of the videos by the makeup/fashion divas and you’ll find a long list of links to places to buy the products they are reviewing in the video description. (You might have to hit the “show more” button.) It is not unusual for them to receive support from the companies that make the products, too.
And here is a music video with an ad for a natural skin care product permanently embedded. (It’s a great song, listen to it.)
Jesus Fucking Christ. Do these 10 million subscribers live on Planet Earth?
Nor will I, a person with untreated ADD, ask them because I lost interest in this scam before I finished the OP. 
I’m a subscriber of Unbox Therapy and I live on Earth. I find it mildly entertaining to watch, and it helps to keep me up to date with tech trends. The channel is successful because, in addition to being pretty much the archetype of the genre, it’s actually very well presented.
‘Unboxing’ videos on YouTube are not usually just someone unpacking a product - if done properly, they are reviews of the product.
Isn’t that a bit like saying Bill Burr is just a funny guy who tells jokes, or Graham Norton just a nice bloke who chats with people? My son watches a lot of the youtube gamer channels and the talent of the top level guys like DanTDM, AliA, Ballistic squid etc is obvious. The majority of people who tried to do something like that would absolutely stink the place out IMO.
It’s certainly true there are plenty of mediocre personalities on there who appear quite popular - they got in early and follow the formula of the more talented.
Do videos of yourself using products from really big brands; eating McDonalds, drinking coke, dropping an iphone in the toilet, then just invoice the company for advertising money, they’re big enough that it might slip under the radar.
