William "Salt" Hale, the Community Director of my non-profit startup Snowdrift.coop, heard me give a pithy and personal explanation of these things in a lightning talk at SeaGL last year, and he requested a video of it. So, with help from my student, friend, and fellow Snowdrift.coop volunteer Athan Spathas, I recorded that spiel and several others about the ways that cooperation and coordination matter in so many areas of life. Athan prompted me with a range of topics, and I explained how they all connect to these social issues.

I don't have answers to everything, I just know some things about the nature of the problems. But that's a good place to start. Too many people today believe a strange individualism that denies the fundamentally social nature of these issues. So, I hope these perspectives provide some value and insights or at least a moment of entertainment.
I may record more such videos given enough requests, and I'll do what I can to answer questions or provide more references and related links if I can find time.
An interesting idea, specifically regarding the problem with using YouTube, is to encourage people you find there to find your video elsewhere. For example, you mentioned YouTube's monopoly status, and the/a solution to monopoly is federation - so there's MediaGoblin, a federated media hostware, which can host your content to solve that problem. Unfortunately, as you mentioned, it will need to be posted on YouTube as well, to gain any attention.
So what I have considered doing is posting a copy on YouTube but disabling the comments section. In the leading line of the video description, you point to the corresponding MediaGoblin page, saying "LEAVE A COMMENT HERE". The user is then free to continue browsing your videos there, where the system is all your own.
