I think a use case as a Kickstarter for unrelated projects would be good for Steem even if some Steem dollars are drained away.

1. increases liquidity increases volume of sbd transactions and increases liquidity
2. . Raises more equityposter must keep half of financing in Steem power. If the user is inactive he will help redistribute Steem to active users. if he is active we won over a user.
3. bit shares might help Steem. many of these tools are intertwined. More money in bit shares could result in more aps that use the Steem currency.
4. depressed sbd price could lead to more buyers if the price gets too low you might have buyers that come for the arbitrage.

Problems.There is an unusual situation where many voters are also interested in success of bit shares. A "related party" issue. This could be abused.
