Would you sell a future neighbor a 15'x70' strip of the edge of your property?

for a driveway? Mrs. TDsngumbo and I are trying to build on a piece of property that's currently landlocked. In other words, there's currently no road access to the property. We're trying to purchase a strip of land 15' wide and about 70' long at the far edge of a neighboring property owner's property in order to build a driveway and access the nearest road. There are two property owners we could purchase from in order to build a driveway to the nearest road but both aren't budging. Our home would be set far away from their homes and hidden by trees. We're not trashy our loud people, and we have children. We're not looking to trash up the area in any way. In fact, we're trying to move away from trash, that's why we want this particular piece of property.

Both surrounding homeowners aren't budging. I think it's an a-hole move on their part but I guess if it was the other way around, I wouldn't want to risk allowing new neighbors who I don't know move in.

What would the OT do in this situation? Keep trying or move on? Go talk to the homeowners in person?

ETA: I'm not dumb - the property will be given to us. We're not buying a landlocked property.
