Because even if your version of WordPress is up to date, if you are using a plugin or an old plugin using a security hole, then someone can use that to get access.
When your site is new, you do consider needing security but you do need to protect yourself and your investment. Having a site go down and not having the ability to restore it may mean a big loss of customers who can't find you and won't remember to look for your site later. Do not let that happen to you. Back your site up as soon as you get it started, as the site is operational, and schedule backups for as long. That way, you'll have WordPress security and peace of mind.
