And words are amazing. All these complex and nuanced concepts we're talking about can be expressed and shared almost instantly because of the words we share. If we had to invent words as we communicated, or worse yet, had no words, there would be no discourse because the sun would go down before we got anywhere.

It is true that words are set in their definitions and intuitions, much in the way that scientific models are and common sense is. These can be considered objective facts.

But challenging these facts and inventing new words is just an important part of the process. Some have more success with it than others, but not looking up what is already known is just wasting your time. Same with not using words that already mean what you mean.

Subjective thought leads to objective facts with fact checking. Objective facts are then better shared, and better learned, because learning is far easier than arriving at them yourself. Learning just takes communication, which is proportional to the complexity of the information. Inventing or discovering new facts requires the entire lengthy and laborious process which is will inevitably include experiments and fact checking and evidence validation if we are to be scientific. If the problem can be solved with pure thought, chances are it was a philosophical one, although philosophy too highly relies on existing language.

The thing with code is that you can take those existing patterns and make them a first-class concept in your program. You're still in "objectively thinking" - still reusing existing code - just in a more compact and safe way.
