for sure but the point is that sewing isn't really necessary anymore. if all the knitters disappeared tomorrow, the majority of society wouldn't feel it . If (say a few years ago) all SWEs disappeared, that would be a problem for a lot of people. The feeling of impactfulness is gone when things are reduced to a hobby.

That may be true today; but the trend is towards that no longer being the case sometime in the not too distant future.
