No you can’t. You still need to spend the same amount of energy per ton to escape earth’s gravity. An elevator does not magically violate laws of physics

Edit: As pointed out below I probably misunderstood the comment I was replying too. My bad

The comment you're responding to is suggesting a space elevator on the moon, so you only need enough energy to escape the moon's gravity.
