You don't have to use Helm - in fact, you probably shouldn't be using Helm (as the whole idea of text templating YAML is... thoroughly ignorant in understanding what Kubernetes actually is).
Agreed 99%, but there is one useful thing that Helm provides over Kubectl+structured templating (Nix/dhall/whatever): pruning objects that are no longer defined in your manifest.
However, that's solvable without taking on all of Helm's complexity. For example, Thruster[0] (disclaimer: an old prototype of mine) provides a pruning variant of kubectl apply.
