It depends on whether you want traffic from Google or from people typing in the domain name. If the traffic comes only from clicking on links, you could have www.asrhiauasdflbasgbaslkdgb.com and there'd be no problem. However, having a long URL or one with hyphens may cause confusion with people navigating directly to your site. If you own www.widgets-keyword.com but not www.widgetskeyword.com, you may lose a lot of high quality (direct navigation) traffic to your competitor.
