Can you make them pay for a well written easement is a strategy to talk to your real estate attorney about including how to get them to think you might be denying access soon which would be their incentive to agree to the easement your Attorney has prepared (that better protects your legal interest) Otherwise can you make them is the same idea of can you sue for anything , people are sued all the time but proving that one was harmed -convincing a court is another, BTW I don't live in a coastal area I live in a rural MN county with a population of 22,000 but I do see a lot of driveways in this area and the county I work in as well as the one I just drive thru to get to work where they have two and three address plates on the post out front in the first parcel and I also see lots of so called flag pole strips of land that connect parcels in the back of another to TWP and county roads. If they refused to agree to a well written easement maybe you will get lucky and it will take them forever and a day to find a cash buyer OR until they get totally desperate to sell and ask you for one instead of trying to find the money to force you to allow access by suing you if you closed off their access which is a talk to have with your atty.
