> True, but in this case, you were able to infer the intended meaning from context, which is what reading is: interpreting text, which involves assigning meanings to symbols and resolving ambiguities to render the whole as intelligible as possible.

Yes, but each ambiguity in a given piece of text makes it harder to infer the intended meaning, in a way that's not linear with the number of ambiguities (or at least doesn't feel so). A missed comma here, an extra comma there, couple typos, and suddenly the text switches from understandable, if slightly tiresome to read, to entirely unintelligible sequence of glyphs that requires approaching it as a puzzle to have a chance at understanding what it says. The threshold for this switch is different for everyone, so it's in everyone's interest to keep your grammar and spelling correct.
