Some of the Rules of Acquisition might give the Ferengie incentive to develop warp drive on their own:
9. Opportunity plus instinct equal profit. (Being able to reach other stars systems gives you the opportunity to exploit them and make a profit.)
45. Expand or die. (A new market would be opened up with warp drive.)
62. The riskier the road, the grater the profit. (The Ferengie who took the risk to open space to other Ferengie would have died richer than kings.)
75. Home is where the heart is, but the stars are made of latinum. (Perfect reason for warp drive. OTOH, this Rule may have come after warp drive.)
263. Never let doubt interfere with your lust for latinum. (There may have been doubt to develop warp drive rather than acquire it, but #'s 9, 45 & 62 could help eliviate any doubt a Ferengie may have had to develop warp drive.)
Something to think about.
