Rather, powers that allow you to heal without spending healing surges exist, but are not as common as powers that do make use of surges. Clerics still have cure light wounds and its more powerful versions as daily utility spells and PH1 paladins can lay on hands Wisdom modifier times per day, which expends a healing surge from the paladin instead of the target.
Some did exist, but they expended someone else's healing surges, so in the end you were spending surges either way. You couldn't just chug a potion, or use a wand, to get you back to a decent fighting capacity.
