That's a common sophism that completely ignores the cost/benefit trade-off of those supposedly useful error correction mechanisms.
In German for example, they're IMO total overkill (as in cost far outweighs benefit).
But then, you have to take into account that over-engineering things is a national hobby in Germany.
The question becomes chicken-and-egg: did the language induce the cultural trait or did the cultural trait structure the language.
Even if you don't fully understand a word, you can piece together from the context what was said.
