Yes, Bitcoin is for everybody, and no, not everyone will get into it for the same reason you did. Some will get into it because they want to get rich, some will prefer the payment mechanisms it offers, others will like the idea of self custody, while still others will just be trying to shield their wealth from inflation. There are those who will use it to hide wealth, and those who will use it to track wealth, some will use it because they're unable to use anything else, and some will use it just because they like the tech behind it. There are a million reasons why someone might use Bitcoin and your opinion about the legitimacy of their reasons or level of understanding is of no consequence at all.

The benefits of having a massively bigger network effect thru usage at the lowest levels of understanding vastly outweigh any potential drawbacks from misuse by a few.

Therefore, everyone benefits when Bitcoin becomes easy enough to use that anyone can use it. And we will get there, even if we have to drag visionless, ivory tower, walled garden pricks along kicking and screaming the whole way.
