That’s not going to work.
If you can’t access your password manager for the actual password you can’t use it to get your security question answers!
There's some logic in your reply, but that's not the only reason for security questions. Many secure web sites drop a cookie that says, in effect, "this user has visited before and has passed the relevant security checks." Problem is I do most of my browsing in private/stealth mode, so the cookie disappears after I log out and close the browser. So I get hit with a security challenge every time I visit the site.
In addition, because I use a password manager, I long ago gave up using memorable passwords on most sites—especially important ones like financial institutions. I need my password manager just to be able to log into them.
