I thought the same until I started hunting for touch spells in the wizard list. There aren't many. In fact, shocking grasp was the only one I could think of without a better search capability.
Vampiric touch? Cause damage and regain hp, all at a comfortable distance.

Also, keep in mind that the familiar doesn't cost you a slot per day. It only costs you a slot on the days you summon/replace it. And that's if you don't cast it as a ritual.
Now, if you meant "slot" as in "one of the spells you start with in your spellbook"... Well, I disagree, but I admit it's debatable.
