If all you wanna do is code, then you don't need a computer science degree. There are plenty of companies looking for people to do form plumbing.
Now, if you wanna do real computer science, yes you will need a degree. By real computer science I mean things like improving performance using algorithm complexity analysis (Big O), knowing when to utilize the best data structures, architectural optimizations, AI, writing your own lexers and parsers - the list is endless.
Computer science is different than coding. Whereas coding is a tool, computer science is the study of any kind of computation. You can implement a quicksort algorithm on C++ or while sorting your own clothes in the closet. Both are computer science.
