"A badly thought out copyright rule may remove"
Why? You assert you don't watch pirated contents. Any video that isn't pirated will stay there, and you will be able to keep on watching it. Instructional videos that don't infringe copyright - and remember there are a lot of fair use exceptions - they will stay there, just like any promotional video uploaded there with full rights, so what are your you talking about?
Or do you mean that without pirated contents YouTube is not a viable business and will collapse?
