I guess you wouldn't be saying "please stop having children" to Satoshi's parents, now would you ?

Of course, I would. Especially considering Satoshi is already born.

If you believe that the planet can't handle more people, do the planet a favour: kill yourself.

That wouldn't be very efficient.
By killing myself right now, it would remove only 1 individual from the Earth population (and I would be quickly replaced by dozens of newborns in the following seconds).
By helping a few people realize that breeding like rabbits isn't sustainable, I might help them to avoid adding several individuals to the world population.

DISCLAIMER: I am not affiliated with the VHEMT, and I don't think we should go as far as letting our species die. I'd rather see Humanity achieve sustainability. Either way, we have to stop increasing our population size.
