The colonies were not subscribers to an indivisible and perpetual union as are the United States. There was no consent from the colonies to be ruled by Parliament which was the essence of the Revolution. These events are completely different.
You are incorrect about this. Every British subject was told and believed that allegiance to the King was perpetual. Refusing to obey the King was treason. That is the environment in which the Colonists were raised, and that is the belief system they held at the time.
There was no consent from the colonies to be ruled by Parliament which was the essence of the Revolution.
"Consent" was not a factor. Thousand year old British law required obedience and perpetual allegiance to the King. The only indulgence tolerated is if a British woman married a foreigner, she could move to another country and no one would accuse her of Treason. For men, there was no manner in which their required allegiance and obedience could be thrown off by them.
These events are completely different.
Only in one regard. The Founders overturned the British law doctrine of "Perpetual allegiance", and replaced it with a new natural law principle that people had a right to independence.
Then Lincoln came into the picture and restored the British law doctrine that Independence cannot be tolerated.
