You said segwit 'buys time', implicit in that statement is an acknowledgement that something needs to be done. Hence I think you already know the answer to your own question "What's the Urgency?"
"No, segwit is far superior in every way (expect a really important one), change subject to something emotive then state some undefined thing is obvious."
That's your best argument?
- Classic fixes full blocks by changing a parameter to allow for bigger blocks.
- Segwit works around full blocks by changing the way in which bitcoin blocks are built, and moving some of the data into a new data structure.
There are pros and cons to both methods (the above is not exhaustive). It is not clear that one is objectively better than the other.
Yet you are stating that Segwit is far superior. How can you possibly know?
You draw a comparison to the "Core vs Classic" debate. The implication here is either that you think Core is far superior to classic, or that you think that its obvious that Segwit is better than a blocksize increase. Its one of those opinions presented as fact things. It also serves to further polarise opinion on the topic.
This is a fact:
- It's not obvious which solution is better.
This is, on balance, most likely:
- Core is not far superior to Classic.
- Classic is not far superior to Core.
This is another fact:
- Segwit and Blocksize increase are not mutually exclusive.
