Not fly with a private jet? It is not an unrealistic expectation. Plenty of people manage to not fly with private jets on the regular.
There is the secondary factor of their time being too valuable as well, and having a direct flight to anywhere in the world making a big difference in how much time they spend.

The intention of many of these campaigns (like paper straws and paying attention to your individual carbon footprint) is, at least in part, to instill the idea that environmentalism should be all about individual action, rather than holding large companies to account for their role in pollution and environmental destruction.
