The vision of future power an money, hope to gain capital - money that make more money.
I do not want to relay on selling my work to make living. I want to work for projects interesting to me, disregard monetisation. And capital can give me money with no work involved, to be free for my own life to live.
I think Steem Power allows for a lot of future potential revenue streams that can help both build and personally earn. It is an interesting way to fund projects in my opinion :)
