Raccoons have no natural predators and since they find tons of food in peoples garbage they don't suffer from natural peak/crash cycles. They also commonly contract and spread rabies and several other diseases/parasites which are very harmful to people. They are also extremely smart, once you trap and release a raccoon you won't catch it ever again. A formerly trapped female will teach her young to avoid an area where she was trapped.
If translocation was legal, which it is not now in many states, 5 miles is not far enough. Their range can be more than 5 miles across. 20 miles would be better but really is not good for the raccoon. Your drop-off becomes an intruder in the new territory and can spread disease/parasites into an area where they might not be present.
And yes, there are more than you realize. One year we had a serious raccoon problem and I trapped and eliminated 23 raccoons. Several more were hit by cars in our general area.
When the fur bounty was eliminated the raccoon population exploded since they have a nearly unlimited food supply thanks to people providing food for them.
Once an occasional visitor becomes and unwanted resident, your best bet is to trap and kill the animal. Relocating a raccoon is dangerous. It is also illegal to do so in Alabama.

As for the "plant enough for wildlife too" adage, good luck convincing the wildlife that they need to leave some for you. I've had deer damage all my melons in one night. I've had groundhogs damage all my tomatoes in a few days. I watched squirrels take all my tomatilloes, sunflower heads, sweet corn and peaches in a matter of hours. And I'll never forget the mama groundhog that brought her babies to devour my lettuce patch in under an hour.
