Question

acids and basses are too dangerous for humans to use daily

Answer 1

That's the weirdest statement I've ever heard. It's not true either.

Many acidic substances are used in cooking. Like vinegar, and lemon juice.

And cleaning detergents are basic. Like laundry detergents, and hand soap.

Answer 2

He stated that basses were too dangerous to use, not bases. It's a good thing I play guitar and not bass then.
