The Anthropic answer to this question is that if gravity were a lot stronger, then the evolution of the universe would have proceeded in a different way, it would have collapsed just after the Big Bang. One can speculate that all possiblities really exists, but we can obviously only find ourselves in those universes with laws of physics that are compatible with our existence. Moreover, the laws of physics will appear to be fine tuned to maximize the probability of our existence. In reality there is no such fine tuning, it's all an observer selection effect.

There is no reason we humans can tell why gravitational force is so weak. We did not create it. We just measured it and found it was too low.
