As for the Tosche station line I don't have a problem with it.
He's a teen, trapped on a nowhere planet, doing a boring job for a domineering dream quashing uncle.
He could leave at anytime but stays out of a sense of responsibility and yet Owen is still ordering him around like a small child.
It makes perfect sense that he would be resentful and whine while simultaneously attempting to justify his limited chances at relaxing from his tedious life as something work related to his ungrateful parent figure.
He doesn't know what Owen's genuine fears are or what is causing him to hold Luke back so he is kicking against what he sees.
All things considering Luke's reaction is surprising mild.
I get that, but it still seems seems odd that Luke would get upset over a simple matter of not being able to buy machine parts right away. If the power converters had been written as a local band Luke wanted to see perform with his friends or something along those lines, it would have been better IMO. As the line is, though, it just comes off as unintentionally funny.
