To me the advantage of eSIM is coupled with dual SIMs, something that wasn't very common in the US until the arrival of eSIM. Now when traveling I can purchase an eSIM instead of pay my operator a ton of roaming fees. But I can still keep my main SIM active, just with data disabled.
It's not that any of this was impossible without eSIMs but it's created a new market of online-only SIM sellers. Before eSIMs I'd have to be without data when I first arrived somewhere new while I buy a local PAYG SIM. Don't have to worry about that any more.

Outside of dual SIM applications I don't think it's a whole lot more complicated than online retail being considerably more convenient than in-person. When switching providers you often have to time it correctly: make sure the plan is expiring on your old SIM when you put in the new one. Having a SIM arrive instantly makes that a lot easier. Plus it's just a lot easier to make a spontaneous purchase.
