I guess I feel like I deserve to keep being paid for pages I have built in the past even when they no longer exist. Arriving to a page with upcoming 2003 events is probably awful enough to make them want to go somewhere else, that's why I wanted to remove the "historical data". The site has about 1500 pages, so yes, they have to find their way around if they get lost on an error page. The error page is meant to be helpful. My thinking is that related ads would give them an additional option, making the page even more helpful?
