First of all AI can't handle it at all, thus they do not get it, which is extremly annoying (seing Kilwa Navy blockading Lubeck, why I can't blockade them for a month or I'd risk loosing whole fleet). So distance during blockades is counterproductive, as it only punishes player cause "he should be able to handle the attrition".
But players also has hard time handling it, as they simply forget about fleets. I doubt if there is single person on this forum who never lost some ships for this reason.
In fact it almost never matters, aside from explorers, It only forces You to pay some minor fleet-basing fees if You want to move Your fleet to the other side of the world.
As for the explorers, it's really the only case in which it really plays any role, but it could surely be done with a less annoying mechanism. It's a small gain for a large amount of frustration. (maybe add damage for entering TI).
