When does corporate accumulation/hoarding become a problem?

Serious question here. With several companies aquiring as much BTC as they can, with no plan to ever sell/use it, when does that start to become a problem?

I genuinely don't believe us small hodlers will see true wealth until this thing is widely adopted and in use, whatever that looks like. So how does owning a shitload of Bitcoin and letting it sit there provide future value? Are we just relying on there being enough new people entering?

Not trolling, looking for genuine discussion.
