Right. And kicking a rugby ball at full strength from a short distance towards an unprotected goalie might hurt. In the video they're only lightly passing and kicking the ball.
Being hit in the face (or genitalia) by a spherical football hurts a lot if the shooter knows how to shoot and you're relatively close. I don't want to imagine what it feels like to be hit by an ovoid ball.
I've only trained as a referee in one sport and it had a "be a sportsman" element to the rules giving the ref leeway to determine that play is unbecoming of the sport and so give away a foul. But in that sport smashing the ball _at_ players is normal.
Sure, if you're playing with pals, or for a promotional video then you're going to be less combatative.
FWIW the rules don't say you can't knee, pull, or poke (eg in the eye!).
Also, the penalty rule sounds impossible - you have to score "from the centre gate", but being in the centre gate is a foul and gives possession to the opposing team ... ah, no, wait: "Moving through the center gate will result in a foul." ... so it's fine, you just aren't allowed to leave the centre gate [does the foul activate from the time of entry or the time of exit?].
Yes you do, just not intentionally. It is common for a player to shoot near the goal line in two ways: excellent placement with just the required strength, or a powerful shot.

Curiously, the NFL--which has the single most pointlessly longwinded and legalistic rule book in probably all of sports--has a similar rule allowing referees to do literally anything at their individual discretion in response to any "palpably unfair" action or situation.
