In shore leave, the phasers, then the communicators the the enterprise itself experienced power drains.
Example: sulus phaser didn't fire at the samurai
Example: Spock calculated he had just enough power to beam down
Now if the power was used to create all the creatures/things for just 7 people...them how the heck were they going to get enough power for 400 plus folks on shore leave?
If the power drain wasn't for that, then why the heck was there any drain at all? (ok, convenient maguffin)
