I don’t even think it’s the eccentricity that does it, all it matters is that the earth isn’t tidally locked with the moon, that’s what gives you the tides: Earth is rotating faster than the moon orbits and so different parts of the earth face the moon within a day. It also helps that the moon is a significant fraction of the mass of the earth, which means its gravitational influence is significant to the oceans.
