Why is there a limit on the number of custom fields I can add?

Why is there a limit on the number of custom fields we can add to each section? For example, I can only add 5 lookup fields or 20 boolean checkboxes. Is there anyway that this limit can be removed, or increased on the Enterprise Edition? It's very important that we are not blocked by these limits.
