The idea of "constant growth" is Corporate ideology that they have poisoned us into thinking its necessary. A hobby doesn't need indefinite growth, it doesn't need to live forever, and it certainly doesn't need to breach other markets.

In can in fact simply exist on its own with its partakers enjoying its existence in their own way until they die or move on. That doesn't make the company absurd money however, which is why they convince people that it needs to be constantly gaining more people and welcoming constantly.

So, as always, Leftist talking points are just them being stooges for the corporations they claim to hate while they whine about not getting the toy they didn't even want in the first place.
