I think a large part of the reason for giving money to a company like 23andMe is speculative; you are expecting that widespread genetic testing will result in us (as a society) learning a lot more useful info than we know now, and towards that end you want to see private sector companies like 23andMe succeed. If all we ever got out of it was what 23andMe (and their competitors) can give us now, it would not be worth it. But, sometimes you need some "foolish" early adopters to get the ball rolling. Plus, there is some entertainment value. If you would not find it either satisfying to know that you helped this industry get going, or interesting to know about the ancestry stuff, it will not (at this point) be worth it.
