It’s not like that.
Greece wants to refinance- make a hundred monthly payments of $110 bazillion instead of 50 monthly payments of $200 bazillion.
So there’s money to be made- as long as the game can be kept going.
But it can’t be kept going forever, not without some major structural changes to the Greek economy, which of course they don’t want to do. Refinancing will stave off disaster for a while, but its just a band aid. Unless they balance the books AS WELL, theyre just going to be heading for another refinance in a few years time.
