Imagine you have a database, you decide to add something to it and now you have to solve 5000 sudokus. Also you can’t remove anything as well. Have fun
Imagine many entities have a shared database. You cannot trust anyone else but you have to add something. The consensus mechanism of the algorithm of your choice ensures that only good actors participate through sheer game theory. This naturally has a cost and you are happy to pay it. You have a lot of fun
So I’m clear, does blockchain always refer to those *coin currencies? Or is it be used for other purposes too?

This is just plain wrong. Blockchain is not a synonym for cryptocurrency or proof-of-work.
