You can't write software without training wheels either, you just think you can.
I know enough about C to know that I can't write it safely 100% of the time, especially when you introduce things like parsing untrusted input and threading. Thinking you can do this safely, and thinking you don't make mistakes suggests you actually don't know as much about C as you think you do.
There number of subtle and unexpected things that cause UB are pretty concerning. Most of our software that we rely on day-to-day is filled with subtle bugs, many of which will eventually be exploited and used for RCE and other nasty things. I don't understand how that couldn't concern you!
To be clear I don't think we should stop teaching C or anything that extreme. I don't think it should stop being used completely either. Mostly just that we should prefer safe languages when possible and practical, or use hardening features when we do use unsafe languages, like bounds checking for example. A lot of times I think we shouldn't even prefer rust, a lot of userspace software can be written in a GC'd language without issues.
