If I want to replace my phone now, I can pop the SIM card out of the slot, and slide it into the new device. Takes 3 minutes and importantly requires no contact with the carrier.

With an eSIM, I'd have to-- at the very least-- do some sort of migration process through a carrier-provided resource. Maybe it's a web-based thing where I can sign in to their site on the old phone and get a QR code to scan on the new one, but I'd be unsurprised if at least some carriers say "gotta come into a store" or put up some sketchy "for your protection" roadblocks. This could be technical incompetence or a dark pattern, but I'm sure they want to keep anything related to bring-your-own-device to be a bit arcane and scary, to encourage customers to buy through the carrier.
