we can find another better solution if enough time is given
Delaying the problem != solution to the problem. The LN is the only known 'solution' so far.
i think you didn't understand, i was implying that with enough time we could find a definitive solution, but without time it will be impossible you know, the same way we found the segwit solution, it does not matter if segwit was definitive or not
you didn't know prior to find segwit if it would be definitive or not....
