Gap insurance for Toyota tacoma

Yeah but I understand that but I have 2 different opinions of it like someone told me I shouldn’t get it cuz it’s a waste money since the Tacoma’s hold there value pretty well and he gave me an example of 2019 n 2020 models with about 15k miles being sold to close to the price of a new one or the same price but I’m honestly open to learning what y’all experienced folks know this would be a first lease for me so I’m trying to figure out what’s the best path to take
