It’s very energy inefficient to leave the ground.

  So is building and maintaining transportation networks of massive proportions on the ground. Somehow that never gets looked at, people just compare the running costs and completely ignore construction and maintenance. Plus the cost of all the deaths it causes, human and non-human. Plus the space it takes up and how it destroys environments. All these are costs. Planes will not be a solution for all transportation needs, but where it makes sense they're great. A flying bus basically, routes can be very flexibly changed depending on evolving needs.

    That's not true. Public transport is factors more efficient than air travel. And yes including initial cost. We build infrastructure to last not to throw it away 5 years later. You need to understand how much more energy it actually costs to bring a plain up in the air and down again. We talk magnitude more energy than trains. We can talk about this again in 20 years when solid state batteries are broken through.and sustainable energy sources are the norm. Air taxi's ate not hard to build on a technical level. We know how to build them.
