I mean, this isn't that different from any number of things you do in real life? You took a car to some destination. It is assumed you didn't change the engine. Took it to a mechanic, maybe they did?

More, many modifications are flat out expected. You filled out a job application, you probably don't expect to change the job it is for. But you do expect that you can fill out your pieces, such that it is a modifiable document while you have it. (Back to the car example, it is expected that you used fuel and caused wear on the tires.)

As annoying as they were to deal with, the idea of having "frozen" objects actually fits really well with how many people want to think of things. You open it to get it ready for use. This will involve a fair bit of a setup. When done, you expect that you can freeze those and pass off to something else.

Transactions can also get into this. Not surprising, as they are part of the vocabulary we have built on how to deal with modifications. Same for synchronization and plenty of other terms. None of them go away if you just choose to use immutable objects.
