This is an oversimplification of the problem. Malicious websites run under a different security model than extensions. Not to say I am for restricting extensions more, but just to vouch for the idea that there is, in fact, a valid and novel point to treating extensions cautiously versus other kinds of software. Even programs running locally and unsandboxed will have to work quite a bit to compromise a browser.
