Assuming you remove all "wasteful" travel, you're still causing more pollution living away from a major hub. Instead of a non-stop SFO to JFK flight, now you're taking a 1 hr Uber (or driving yourself) to a local airport, then taking a connecting flight to SFO.

You're still in a bubble. Taking a flight for a business meeting is wasteful. Full stop.

You’re clearly extrapolating your own experience to everyone. And have never done sales.

Doing meetings, serious meetings, over Webex sucks balls.

If your some developer who never has to talk to anyone, then sure, your unproductive team meetings don’t have to be in person.
