My understanding is that the Irish scheme doesn't force any specific work for the three year period, though I'd expect any artist who takes a three year, ~$60k grant and uses it to do literally nothing may find it hard get a grant in the future, potentially ending their art career. Still, I wouldn't be surprised if a few recipients end up doing that, in which case it's an economic question as to whether the net loss from such freeloaders is more or less than the cost of the bureaucracy necessary to prevent them.
