I think you just need to set the kill-read-only-ok option.

    kill-read-only-ok is a variable defined in ‘simple.el’.
    Its value is nil

    Documentation:
    Non-nil means don’t signal an error for killing read-only text.

I'm guessing ERC marks only some of text as read-only via text
properties.
