Overall, I must disagree.

1. While there are genuine cases like you, there are also a lot more spammers out there. There's also the problem of new users who don't really understand how SE works.
2. You journey doesn't necessarily start with a question. You can also write answers. If you want to start with a question, you can write share-your-knowledge questions (that you answer yourself), perhaps guides on something you found difficult and you think hasn't got much attention here.
3. I have seen a fellow get 200 rep in one day (the daily threshold) from a single question and the answer that he posted to it. (This wasn't a share-your-knowledge question - but a proper problem that went through a bit of work.) That's enough to set him up on all other SE sites.

Be careful with share-your-knowledge questions, though. You should be clear in what you're asking. Here's a classic (IMHO) example of this done the wrong way: Does Libre Office have an equivalent of OneNote, or is there another alternative? Every single answer (including mine) bar the OP's answered the title and not the body, because they asked different questions. The question was edited, but you can see the original in the revision history.
