Succeeding a small percentage of the time results in dramatically more success than having no one even try.

Also, you're promoting defeatism. If it's just you and you succeed 1% of the time, it still helps a little. If it's millions of people -- even if that's a small minority of the population -- and they each succeed 1% of the time, that's actually a lot of groups getting converted. And it's more likely to succeed the more people in each group who do it.

So the conclusion should be that everybody should do it, since that improves everybody's odds, rather than that nobody should.
