Not everywhere in Europe..., In Slovakia 3/4 operators have single-use QR codes (and for the 4th you have to first remove your eSIM from your old phone before transferring to new, which wouldn't help in case of broken/stolen phone) and none of them have an easy to use web interface to generate a new one, you have to contact support somehow for them to generate it for you.
One operator even charges 10€ for a new QR code for your eSIM (same price as getting a new physical SIM card).
Reading this comment and others, it sounds to me like legislating the carriers and phone manufacturers to force them to make eSIM more user friendly would work just as well (or better?) as legislation to mandate physical SIM slots.
Yes, definitely. And while we're at it also force them to support eSIM smartwatch profiles. In Slovakia 0 carriers support them, not even Telekom, which supports them in 4/5 neighboring countries..
