The Empire was willing to continue the centralized system forever.
They were desperate to maintain the system. However, it was unreasonable and unhealthy for the country to maintain the system established during the war after the war.
During the war, 2000 senators submitted a petition to the Senate, who were opposed to the abnormal centralization.
However, they were resisted.
⚪︎Removing centralism would destabilize public order throughout the galaxy
⚪︎Removing it as the end of the war draws near would mean missing a chance to win the war.
⚪︎Even though they had worked hard to free the Senate from corruption, it would go back to the way it was.
In the end, they did not discuss removing centralism in depth, and the Empire was formed after the war ended.
The Senate was only concerned with dealing with the threats in front of them, and did not think carefully about how to deal with the aftermath of the war. This is tantamount to admitting that they did not need to give up their emergency powers.
Declaring victory, timing for returning emergency powers, normalizing public order, detailed process for disarmament, timing for forcing surrender, process for decentralizing Republic resources, cessation of fighting throughout the galaxy, restoration of authority of the Senate, etc.
Rather than thinking in extreme terms about whether to de-centralize or not, it is better to gradually de-centralize.
The reason why centralization was desired in the first place is that the corrupt structure of the Senate was wanted to be eliminated. However, the authority of the Senate must not be lost forever.
The authority of the Senate should be optimally restored without returning to the corrupt structure before the war.
This was a great opportunity to normalize the Senate, and the Jedi were waiting for this moment.
The Republic government would have overcome its long-standing challenges and become a wonderful nation.
In the end, it did not come to fruition. The only person who thought about post-war management was the Emperor. The Senate was deceived by the Emperor, but was given a large reward by the Emperor and supported the eternal maintenance of the centralized system.
