They are probably either looking to get quick bucks or not in the mood to get involved in the community. People stay in a particular project because they might have discovered the niche they want and somewhere to stay, like here in the forum. Then that will be the part where "long-term" is the goal.
If you think about it, a quick build project could look better. It's a baby, and are you sure you can take risks with those kinds of projects? I don't think people will jump at that opportunity unless you can.
I totally agree with you because that's who I am and as an investor ROI and time are our biggest concerns. This is a very real problem. After all, participants in the current encryption world treat tokens as simple buying and selling behaviors, not beliefs. In other words, the interest relationship between the user and the project party becomes very simple. Making money is a long-term consensus. If you lose money, the user turns around and leaves.
