No. Even with decentralization, we still need to have institutions, authority roles and hierarchical coordination.
What changes with crypto is that it gives people the chance to choose (a) who they affiliate with (b) on what terms and (c) allows unilateral disassociation at any time.
Think of it this way: imagine if getting citizenship to any country in the world was something that involved no bureaucracy and could be as cheap as getting a cellphone sim card.
Save from mass incarceration, there is nothing that authoritarian governments could do to stop people from participating in other economies. People would suddenly be able to participate in a "global market of governance models" without even necessarily having to relocate physically.
Authoritarian governments will of course try to stop this, but my bet is they will lose all type of support when the technology is accessible to the middle-class and they get to compare their relative status with the whole world, not just the local society.
This would lead (I hope) to the realization that governments are only necessary when they serve the people and that will be the most important piece to fix the current broken lack of "checks and balances".
We've got a glimpse of what could happen because of the pandemic and the millions of people who realized that they could do their job from anywhere in the world, and how lots of countries responded by offering "remote work" and "digital nomad" visas. Now imagine if more countries acting like Estonia and start offering "e-residency" programs. The countries would start competing among themselves to see who can attract the most people / most productive people.
It's the possibility of self-sovereignty that is important, not the actual realization.
