Ok, first you are throwing buzzwords and tautologies around.
Second, it is individuals who are corrupt, as only an individual CAN be corrupt. A "corrupt system" is just a group of corrupt individuals in charge of a system. It is impossible to have a corrupt system without a single corrupt individual (ESPECIALLY a centralized one). The problem with a centralized system is that it ENABLES those corrupt individuals to cause a lot of damage. A decentralized system seeks to defang and depower the corrupt.
Besides all that, the biggest issues that crypto was meant to tackle is government incompetence, not corruption.
Yep, to touch on the last part of your post first, i'd say that the incompetence of the system is due to corruption. The incompetence severely hurts most people, but I think we'd agree that a few people are highly rewarded regardless of the overall incompetence.
I agree, it is the individual who is corrupt not the system necessarily, while it is the type of system he/she tries to engage his/her corruption on that becomes corrupt as a result. Where the corruption of an individual is best rewarded or put to use is where the corrupt individual will go. History is proof that increased centralized control always leads to increased corruption. The balance of that is not important, but we know left unchecked that increased centralization will manifest corrupt outcomes and results.
Here's a decent write up that has some tie in's to systems and indviduals who excell in them, with a direct example being the government in the USA.

A centralized system is alluring for and rewards the corrupt individuals and corruption while that same system is punishing for those with integrity or those who choose to not use corruption. That would be another way of looking at my position on centralized systems. Basically they will draw in the corrupt because that is where corruption has the highest reward, their may be individuals full of integrity in centralized systems, but they will be at a disadvantage in such a system to those who are corrupt. Over time the corruption will win out. That's why IMO the responsibility is on designing and maintaining a decentralized system, something Bitcoin is failing to do over time due to centralized hashing power centers that are winning out. If the mined bitcoins spread to more individuals that is a good thing, but the centralized control of the creation of bitcoins is in the long term a value defeating side of BTC's future.
Bitcoin can't upset the status quo if it becomes the same as our current status quo, and I believe BTC gets 90% of it's value as an alternative to the current status quo of trade through USD and other nations currencies.
The IRS ruling is bad on top of this because it essentially destroys btc's place as a fungable means of trade. Bitcoins become different than eachother based on when they were bought (at price $10 vs price $350 becomes 2 different bitcoins based on IRS rulings) and btc's really need to all have same value if they will be used for trade.
Overall I'd say that without question there needs to be some form of response from the BTC community, but from what I see BTC will simply be pushed out of the USA into other countries.
