You don't need to use an e-sim if you don't want to! Galaxy devices still have physical sim trays for people who prefer using them - e-sims are just one option for people that find it more convenient: for example, people that have multiple devices, or frequently swap out their phones.
Only Samsung flagship devices that have an eSIM For me, I own a Samsung flagship phone and am planning to get a Smart eSIM, but I'm still thinking about it
