If you really think about it, such organizations don’t need any license. You trade on the Internet, who said that the trading operation is carried out on the territory of this particular country. By and large, the only problem is for the user when he wants to withdraw crypto into fiat. Or am I missing something?
Technically you're not wrong, but that's not how things work. Although business is carried out over the internet, it also has different regulations in each country. And not only when a user decides to withdraw their funds (or part of them) to fiat. When a user trades cryptocurrencies and makes profits, they must declare them to their country's tax office, as regulations force them to pay taxes on those profits, because economic wealth is generated, regardless of whether those benefits are received in crypto or fiat.
There are still countries (less and less) with very lax or non-existent regulations; Dubai, Portugal, Switzerland, Malta, and Singapore are some examples. But that doesn't mean they will one day propose regulations or make existing ones stricter.The user is ultimately the one who decides how to do things, like not using centralized exchanges, for example, and make things less comfortable, but always a little "more secure" and anonymous.
Below I leave a table with the countries with the highest tax rates on cryptocurrencies:

And now the table with the countries with the lowest crypto tax rates:
