Yes, I agree, if the account would be growing with regular Upvotes, that is what anybody can contribute without much giving away and if account would have high value of Steem Power then it would be easy to help too. Currently regular posts from Helpfund accounts generate regular Steem Power but that is still very little considering the amount that is needed if it decides to donate.

Like any project it needs more visibility, support of users around on Steemit and also some encouraging words that is a driving force for anything in this life, because again we are human, often inspiration, encouragement alone can motivate. There was a lot of negative publicity about WOX recently so we need positive vibes too.
