Well just as advertising these days it takes around 20-30 times before someone will truly become a loyal follower. But yes boost for just something short term will of course never be of that much point. Same as if I upvote and support a person for months and then they go do some other thing then that was an investment where I lost it all. Since they stopped.

The future is targeted advertising like when you reply to someone in a comment. You can focus in on that specific person and create a niche reply that has a high likelyhood of success. Majority will clearly try to boost something and then quickly cash out since almost nobody knows how to build up a cool name. This Internet thing is still very new to people and it doesn't come with a manual for how to use.
