Android now lets you transfer eSIMs between your phones

No. Once every few years. However, the gap in service is absolute disaster in modern society. Without a phone, you can't use public transport, can't pay for parking, can't get a taxi/uber/competitor, etc. etc.

Any "progress" that makes the turnaround time longer when your phone breaks is a horrible and unacceptable downside.

For me it's about every 1 to 2 years, but I'm an app developer part-time so I use it to make money which justifies the high cost of ownership.

For my wife, it's more like 4 years, and we prefer to get last year's model especially with today's update commitments.
