I'm that kind of person, but my opposition to the "digital key" things like this is mainly about them being out of my control and not having the ability to opt out of user-hostile activity. With a digital key, I expect things like the parent said: being forced to use proprietary corporate apps, facing random limitations like maybe the key stops working if you lose internet connection (or when Cloudflare decides to block you, or anything like this), useless error messages that don't let me know if I can resolve something easily myself, and such things. I do use and like the "digital key" things sometimes, when they are as free and reliable as the "physical key".
