Sadly though, not expensive enough to actually prevent anyone other than the very low end of consumers from hoarding domains.
I worked for a registrar for a decade+ and worked with a lot of hoarders. Very early on in my career I actually dobbed one in to our local registry authority (because I was naive, and he was CLEARLY breaching the requirements for our ccTLD and so I thought 'Well this is wrong and I should report it') and is how I discovered nobody actually cares about hoarding and just wants to maximise revenue. (Well duh I suppose.)
