There are a couple of options for acquiring crypto without KYC. One might sell goods and services for crypto (I have done it myself, sold a videogame console P2P through a local libertarian group chat), or buy crypto with cash via P2P or in a country with looser KYC laws, and lastly they could just mine it themselves. Having significant money through mining might seem improbable, but we can't forget the market dynamics, someone might have mined a lot of some altcoin before a big boom (e.g. dogecoin) and ended up rich overnight.
Also, let's not forget Monero. Even if you buy Monero in a KYC exchange, the letterbois can only track if you've bought, but can't track where you send it to next. You could then exchange it for bitcoin with someone or using a non-KYC service, and there you have it, an anonymous BTC reserve. Or you could just bypass BTC altogether and use the much superior Monero to buy whatever you want.
That whole comment is "With a way harder method than going to the ATM".
I understand that it's possible to get crypto through obscure methods. However if you're selling a privacy focused solution, ideally you shouldn't have to spend 3-4 weeks to acquire the funds to purchase it.
