Will spain ban calls and puts as well?
Right, because it's not gambling, there are different regulations around gambling. All they need to do it GET their gambling license and they can continue, but in this case they will need to follow those regulations. Such as (Italy in this case):
Offer self-exclusion tools for vulnerable players;
Implement identity and age verification procedures;
Comply with anti-money laundering (AML) regulations and GDPR for data protection;
Pay online gaming taxes, which range between 20% and 25% of gross gaming revenue.
