Good on you for realizing that safety, and the law, dictates that a motorist must sometimes wait behind cyclists for a safe space to pass.

The situation you posted is such that you literally can not find this space for 45 minutes?

No, it is not unreasonable to expect road users to be aware of, and work with each other.
I often take the lane for my safety when riding by myself, and always do what I can to facilitate overtaking when possible. In the situation you described, I would not include myself as part of a huge blockade.
