[Star Wars] In The Last Jedi Yoda appears as force ghost to speak with Luke and make lighting strike a tree, setting it on fire. What stops him from appearing next to Kylo Ren, Snoke or even Darth Sidious and do the same but right on them in an attempt to kill them?

Calling lightning from a cloudy sky on a rainy planet is one thing. Calling lightning from thin air inside a climate-controlled environment such as a spacecraft is quite another.

Nudging the weather a little sounds like it would be a lot easier than spontaneously manifesting lightning, especially when you've got no body and therefore no bioelectric field.
