If my phone breaks then I can scan a QR code or use an app to assign the e-sim from my home network to the replacement phone. e-sims only need access to the internet, not the network, to be provisioned AFAIK, and it can be done automatically at any time of the day so customer service reps don't need to be involved, unlike a physical sim card. Last time I signed up for an e-sim, I just had to have wifi, and the whole process was about 15 minutes. What happens if my phone is stolen with the sim card, or the sim card breaks while I am away from my home country? Literally all of the problems you cited are not solved with regular sim cards. Getting set up with an e-sim can be as easy as: download app/scan qr code, and provide payment info.
