The question is kind of misframing my point(though respectful and constructive, as I have come to expect from you). There is nothing keeping 1000's of businesses from using the bitshares platform, but we have to provide incentives for businesses to want to do the opposite of what we see today. It is a matter of incentives...and a delegate to subsidize your freedom-loving (3D Printing, free energy) business is a huge benefit. This is especially true if competitors are monitoring each other in hopes of taking eachothers' delegates. I think the incentives are absolutely critical.
It isn't just that we reach a high marketcap, but also how we set the foundation for that growth in a way that incentivizes companies to see bitshares' citizens' rights as the number one priority.
But this is not the point of the OP.
The incentive should be the utility that BitShares provides. There is no point in a product that need subsidising .. bribing users is a short term indicator that something's wrong. If the timing is wrong, then wait a while and find a different class of user/audience who will engage at this stage.
If it's a matter of bridging that gap in time, then approach Richard Branson or similar.. he's apparently hosting some Bitcoin summit roughly now:

Perhaps what we need more that what is typically PR, is ambassadors. The best will be those close to the core dev team who can communicate exactly on target what is possible and inspire that support.
Trifold brochures etc are all very well.. but who's getting the message? The measure of PR/Marketing is the volume [quality x quantity] of the message they are creating. It's unclear that the message is getting out or to the right people in the right way.. perhaps it is and we're suffering the natural evolution of BitShares class of activity right now, coupled with pressure on BTC from merchants turning it over. Perhaps the halving date in 2017 will be the next uptick. Plan for worst case and enjoy the difference..
