Sure but for a long time web has been touted (rightly or wrongly) as this safe sandboxed convenient distribution platform. The expectation is very much still that a website shouldn’t be able to harm your computer and that expectation isn’t going to change any time soon.

In top of that, less technically inclined people don’t even expect native applications to be able to harm their computer and we haven’t been able to change that expectation.
