If you ban any single activity you're not going to stop polluting the planet... Because there's no single contributor, so your options are to do nothing or stop everything all together? None of them are feasible.
I don't even think you have to ban private jets, just tax them very heavily (because they are plain luxury).
I thought Romeo was a teenager too? I mean, the difference in age should be around 3 years they are supposed to be 13 and 16, although the age of Romeo is really never specified, I wouldn't say it's that problematic.
I find Anakin and Padme, or Bella and Edward more problematic, and there's not much outrage for those.
