I would like to see Bitcoin returned to its original form without ordinals but wonder if that is even possible at this point.
It will be hard to do so, yes but it is possible. Many people are constantly trying to look for other improvements and upgrades so I am pretty sure that one way or another we can get one to reverse the impact of ordinals.
I would like to start a group who advocates for Bitcoin as it was intended. Is anyone interested?
Your passion is amazing and you can definitely do that. Just make sure that you have a clear and detailed points to present to the community. I am sure many share the same sentiment as you, me included.
