Lasers still expand over time, and can expand more with lenses, so it isn't like hitting a laser pointer sized target.

That's right.

By the time the laser reaches the target receiver it could be covering an area of tens of meters, or grater, and still be usefully detected.

Think about the tiny amount of energy emitted by a mobile phone transmitter and still able to he usefully detected by an antenna on a tower kilometres away.
