There are not kind of master nodes that don't allow purning, to help avoid "fail to sync"?

I don't understand how you think that would work... If your name begins with "A" you would only be permitted by the UN to run a non-pruned node? :)  In practice this isn't a concern today because only a few percent of nodes are pruned.

If all nodes were pruned a new node would keep making connections looking for an unpruned peer forever and fail to sync. If instead almost all were pruned it would simply take a longer time than today to get connected to them and start syncing.
