While I can appreciate what Hamill says, when he gets to that part about going away for 6 months or whatever to regroup, etc, one can look back at TESB and before that RofS (episode 3, a prequel) to see that Yoda, arguably considered the greatest Jedi of that time period and the one always looked upon for answers and how to handle things, himself decided to go into exile on Dagobah for at least 2 decades as Luke was sent to Tatooine with Obi-Wan to grow up and Luke doesn't meet Yoda on Dagobah till he's roughly 30 years old or something close to it.
So yeah, in the face of insurmountable opposition there's not really much else to do but run off and hide till some point in time when opportunity presents itself.
And Lucas himself wrote 1-6 so, if that's not considered to be "the ways of the Jedi" then I don't know what the fuck would be.
Slightly different though, in the first case you have a Jedi order going into hiding pursued by a galactic empire (and as A New Hope tells you still known/active within the rebellion) whereas here Luke has a runaway apprentice who have murdered and destroyed his pupils.
