What I remember from my youth (60s): you basically weren't allowed to strike-through, you had to start over the sentence. Many kids thus would learn to write without making errors, making sure you would think ahead about how to formulate properly while writing.

This also has assisted me in thinking before I speak.

The presence of the backspace key has spoilt me. I hardly write anything with a pen and paper these days.
