It's not nonsense, it's pragmatic. Everyday written English is littered with wrongly-placed apostrophes. My friend's English teacher had an apostrophe rule: if in doubt, leave it out. We need them much less than most people think we do and the Germans just use cases instead
You can't just do away with apostrophes with no replacement. They change the meaning of words. I love Eats, Shoots and Leaves by Lynne Truss for all the examples she provides that demonstrate how the removal of an apostrophe changes the meaning, the legal document examples are especially interesting. (to me!). The iPad is terrible for this though, yesterday I noticed (after posting )it added an apostrophe in yours where I didn't want or need one. I do agree with you however that there's little hope for grammar/spelling over the coming decades.
There are two types of pedants: conservative pedants and liberal pedants (I'm the latter). I believe that the English language is changing all the time (we'd all still be speaking Gaelic/Norman French/Old English if we were to have stuck to the rules, historically). I think we should just do away with apostrophes, such is their widespread misuse. A conservative pedant seeks to preserve the English language in aspic, much like the Académie Française.
Written English is changing rapidly at the moment because we all wrote more, anymore often, due to social networking, texting etc.
