if youre literally learning to ski, leave em if you want
if you are anywhere between novice and "very good," USE THEM. it will make your skiing form much better and then if you want you can drop them later once youve internalized good technique
you'll still look like a goof slipping around in the lift line like a 5 year old, but that's your prerogative, right?
as you can probably guess, id suggest getting poles.. you don't need anything fancy, just get the cheapest ones that you don't mind holding
