“Profile” can be used interchangeably instead of “Account”. One can “create a profile” and “delete a profile” and “follow a profile” without too much mental gymnastics. 

“Sign Event(s)” is a little more of a hurdle, being ephemeral. People are used to “signing in” and staying “signed in” until “signing out”.  The nostr ecosystem is just more complex than this… and the mental burden is unavoidable.
