Right, and if you disabled 50% of the language, you would also have a better codebase, but the trade off is going to be that any development is probably slower.

Programming is about trade offs, and typescript offers you a fixed set of tradeoffs - much more project complexity for type checking ahead of time. That can be valuable in some instances - when one codebase has to be shared across a lot of team members that are unable to communicate well. But typically the better fix is to break down and modularize code so that we smaller, more easily managed pieces that can be handled by just a few hands.
