That is just the way it has always been with the mainstream comic book companies. Sure, some smaller companies, who tell grittier stories, are more realistic on this stuff, but not the big boys. How many times in his career should Batman have been locked up for all his law bending and breaking. Vigilantism is generally against the law, after all. But comics say the greater good is more important than punishing the heroes. Plus, how many of them would continue to be heroes and protect the world if they thought there was a real chance of jail time? And as for the MCU, I think that if the Sokovia Accords were not needed to advance the plot and story for all the future films, it probably would not have been in the movies at all.
