The original promise of bitcoin was that it would actually be useful as a currency, for buying stuff. Now that this hasn't panned out, and the problems preventing BTC from being used as a currency fail to be addressed, advocates have shifted the narrative to "bitcoin is digital gold".

IMO, if the Netherlands bans bitcoin, they will also ban other similar cryptos that could actually be used as currencies. That negatively impacts the crypto markets for sure. It's not just about bitcoin.

Would such a ban be hard to enforce? Sure, but not everyone feels comfortable doing things that could land them huge fines or even jail time. I certainly don't.

Gold is used as a store of value because it's been universally recognized as valuable for thousands of years, in almost every culture. Would you really trust your life savings to bitcoin if we're in a climate where more and more countries are banning it? That would make redeeming your digital gold increasingly more illegal and difficult. Crypto bans definitely erode the "digital gold" proposition as well IMO.
