my preferred path would be to forego more and more users in favour of a few very good bloggers who could ensure an exceptional quality of contributions on the platform and thus a unique selling point.

This can be achieved now without the need for any change. There is actually nothing stopping anyone from creating something like Medium and leverage the Steem blockchain to do it.

But people need to understand that the utility of the chain goes beyond it social aspect. For example, if we are discussing blogging here because we are on Steemit.com, another platform or project could be discussion games or any service that can be built on Steem. It can be an ecommerce, a game, and any other business model that can take advantage of the technology that Steem is offering. This is why we need to be careful to not undermine the utility of the blockchain when thinking and applying future changes.
