I missed this part.  Views and prepared queries are not the same time.
Use of a view still needs to be optimized.

Prepared queries will run the optimization portion on the entire query
including the view segments of it.  Think of a view as a MACRO.
Depending on the context of what surrounds it, the view may be executed
very differently.
