I've travelled with my eSIM and switched carriers domestically. I've also switched phones. Here are some samples of why it doesn't have to be a problem:

- AT&T makes transferring iPhone - to - iPhone trivial; offers to transfer automatically during setup

- Visible provides an example of a simple app that can install an eSIM on your new device without talking to a customer support rep or waiting for something to come in the mail;

- The previous also applies when moving between competitors - means one can switch carriers in an hour from your living room

- Traveling to Greece with the Airalo eSIM app was trivial to set up (open app, search country, pick data package) and while I'm sure I paid more than I could've if I'd found a local physical SIM, I was able to set it up before leaving the US so it worked instantly the moment we landed, and the app made it easy to track data usage and reload if needed without phone calls or local apps.
