Among other factors is parasocialism, thus creating demand. Combine the fact that they may still not be into "PARASOCIAL FUCKS" level, so they're too lazy to go from one place to another to search for the desired card.
Protip: they are what the majority of Hololive ID fans call "oknum", "not true fan", etc. No true Scotsman fallacy.

Then, when some people obtain billions of cards (especially non-hologram ones), they may consider selling some of them, especially in the current economy. Thus, creating demands.

Just like Prohibition or when the government tries to eradicate pornography, it'll fail to stop people from doing the very thing that Hololive ID (and overall Hololive) fans despise.
