A lot of people will judge you for not having a college degree, and choosing not to get one will put you in a position of either having to just accept that or work harder to prove yourself (and you may not even be given that chance).
Also choosing to forsake a degree just plain blocks off a lot of paths. Say, in your late 20s, you decide landscaping ain't for you, and you want to become a doctor. If you never bothered to get an undergrad degree because if some impression that the direct value wasn't worth it (e.g. I don't need those "networking connections"), making the switch got a lot harder: you're going to start from square one, at a life stage where that will be more difficult. If you already have a degree, you can get in the position to take the MCATs and by rocking a semester and change worth of basic science classes. Landscaper -> doctor is a pretty extreme example, but the same situation applies to other areas. I know developers who switched careers from other fields. I don't think they'd have been given the chance if they went high school -> landscaping -> coding bootcamp. Even (early in my career), I knew one developer (who was pretty good), but only had a 2 year associates degree, and the fact that he lacked a 4 year degree hobbled him in many ways.
