That really puts it into perspective. If we each chipped in one penny per video we could replace advertisements for everyone. At least in terms of supporting the content creators.
How many videos do you watch per day? If you're anything like me, i at least skim through 100 videos a day. Likely more, depending on my free time and interest.
That's like 1-2 dollars worth of 'penny' donations per day. I'm not sure i would be willing to pay that, esp. if for videos that i'm only mildly interested in, and would not have gone to watch if it weren't free.
