Disable page access via query vars

Question

I'd like to disable the default WP query vars (p, attachment_id, etc...), and make the pages only accessible by URI Permalinks.

I've taken a list of variables from WordPress Query Vars and created a small function to disable them, but it's probably not "the way" since it gives weird results (most of the pages aren't properly routed).

Thank you!

function disable_query_vars($vars)
{
    if (!is_admin())
    {
        $disable = array('m', 'p', 'posts', 'w', 'cat', 'withcomments', 'withoutcomments', 's', 'search', 'exact', 'sentence', 'debug', 'calendar', 'page', 'paged', 'more', 'tb', 'pb', 'author', 'order', 'orderby', 'year', 'monthnum', 'day', 'hour', 'minute', 'second', 'name', 'category_name', 'tag', 'feed', 'author_name', 'static', 'pagename', 'page_id', 'error', 'comments_popup', 'attachment', 'attachment_id', 'subpost', 'subpost_id', 'preview', 'robots', 'taxonomy', 'term', 'cpage', 'post_type');        
        foreach ($disable as $var)
                unset($vars[$var]);
    }

    return $vars;
}

add_filter('request', 'disable_query_vars');

This is definetly not the way! What you mean by "URI Permalinks"? Almost all permalinks lead to index.php and there, WordPress creates new WP_Query in order to bring you the result. Each time you request a page and unsets variables, you makes it imposible for WordPress to bring you proper results, if any.
