Yeah if you want to do the same community it’s going to be harder, but if you want to make your own community with your own content and views it’s different.

Also, the history of the internet contradicts your point, communities have moved servers since the beginning, there never was a unique central point for everything. Lemmy is a bit inferior here because it only allows you to see communities one by one, but piefed can group communities into feeds that you can directly follow. By not placrng focus on a single one piefed can push for much more diversity
