With technological developments, every country and its citizens will certainly follow every development, including crypto. Of course, if it is legal in a country, it will no longer be difficult for its citizens to do anything with crypto. But if there is a ban, it is certain that there will be people who will try to do it illegally and, in technology, it can be done and there are many ways. But breaking the rules is certainly not good, because it will be dangerous for him, even though he has the opportunity to make transactions.
You're right that breaking the law isn't a good thing, but just like you said, there'll always be people who will break those laws, so if you're going to be a law breaker, then it shouldn't be laws that infringes on another citizen's fundamental rights or that'll cause harm to you, other citizens or the society at large.
Most governments places a ban on crypto because they're scared of the height crypto might attain in the future and then try to contain it, so those laws are mostly for their personal and selfish reasons and nothing more, so breaking such crypto laws to me isnt really an actual crime.
