You absolutely can. But it does need an internet connection for that. Which actually makes eSIM more secure than regular SIM.

It can be more secure, but it also feels like the kind of "improvement" that's ripe for exploitation. When you put in a step where you have to ask your service provider for permission to swap the SIM, buckle up for the inevitable development of them asking for a $5, $50 or $100 "service fee" so they consider allowing it.

Couldn't they do that with physical SIM cards? On their end, record the IMEI of the first device they see connecting with a specific SIM card and then disallow connections if that SIM is used with a different IMEI.
