I'll admit that when they say "efficient" that word is doing a lot of work.
Disincentivizing private jet usage simultaneously incentivizes alternatives, the most analogous of which is buying at ticket on a major airline. Those airlines operate at economies of scale and are far more efficient in their use of fuel/person/mile than private jets. Less analogous alternatives would be setting up a remote meeting or phone call.
