It's no easier for a local to be there... you've got a beef with Disney Transportation and somehow are extrapolating this into a locals vs resort guests thing. If you don't like Disney's transportation constraints for a situation - DON'T USE IT. Nothing is preventing you from hopping into a car, or calling a taxi, or an uber, and getting there on your own accord.
"Disney transportation sucks" is not "its easier for locals" garbage. It's simply people needing to acknowledge Disney's transportation is not as time efficient as someone providing their own transportation. This has nothing to do with RoTR, BGs, opening times, whatever.. it's just simple common sense. In isolation and in low scale, having your own vehicle is going to usually be more efficient than a interval based bus.
It's amazing people are huffing and puffing about this WEEKS later, stressing over how to plan, etc.. when a simple one-time $15 uber ride eliminates 100% of the grief.
You're dreaming up new complaints and comparisons.. trying to label things.. and just getting it all wrong because you can't figure out how to focus in on what your actual conflict is.
7am or 8am or any am - it doesn't make a difference when your actual complaint is the amount of extra time you have to account for because you are relying on the free Disney buses.
Instead of buying one over-priced t-shirt... spare yourself all this grief and get a car/taxi/uber this ONE TIME to deal with RoTR access.
