I guess it’s a security measure

I would have thought that access to my Discourse account was proof enough that I should be allowed to change the email address

It is a security measure - and it only applies to Admin accounts. Among other things, email serves as a form of two-factor auth for admin tasks, like downloading backups. If your admin account was compromised and the email could be changed without your knowledge - they could simply change the email to get the backup. This feature prevents that.
