Perhaps I do not understand your point clearly, so I would ask this; how do we emulate this decentralization? Is it by having a decentralized government? Which obviously can't work or you could put it to me clearly so I can understand, I'm open to learning!.
One big limitation that might accompany the adoption of Bitcoin as legal tender for most countries still dragging their foot towards this adoption is the issue of tax regulations , inadequate consumer protection, Financial institution reluctance, I will also add concerns to the environment.
This are obviously not limitations to Bitcoin adoption but a prominent excuses from the governments to justify their ridiculous decisions to attack Bitcoin directly or indirectly.
If we must emulate this decentralised infrastructure in our everyday experience except for the concern of taxation and consumer protection I have the notion that every other limitations can be discarded and treated as irrelevant.
There are obviously irrelevant even the taxation and consumer protections.
Take the financial institution for example this set centralised entity has done more harm lately than good to the wellbeing of their consumers right. And because this act is been fueled by most country leadership the citizens just have no guts to complain but rather endure and tolerate this excesses.
In the process of being a Bitcoin enthusiast it's not proper to look at the downsides of the traditional banking system. It also has a lot of goods so we must put in consideration both the positive and negative aspect of the centralized financial institutions. In a big fan of privacy and freedom but at some point I have to acknowledge the good works they have contributed to the world.
In my humble opinion decentralisation will do our world more good especially now the centralised system of government is having lapses and loopholes
Decentralization would do more good in financial sectors but we cannot say we need a decentralized government it's obviously not a thing rather we need a more philosophical leader who can see from both side of the social lens.
