Exactly. Youtube isn't a means to monetize, necessarily, that comes with audience regardless of platform. If a majority of people switched off of youtube, and began doing their content independently the monetization would inevitable have to follow the content creators, regardless of platform. That's the problem here. Youtube is not necessarily good for content creators, but rather gives a centralized platform for ad agencies to sponsor their products.

However the future is in platform being irrelevant, and acting only as a communication protocol for data. This will allow for both building communities, and since it's only a protocol greater freedoms for content creators, and also greater freedoms for companies to sponsor content creators as they won't be restricted by another organization's policies.

Youtube will ultimately just be major news network spam, with reduced diversity. You can already see late night show spam, and news organizations getting preferential treatment on the platforms. These organizations will never be adequate for the internet due to their bureaucratic nature.
