Is this a non starter also? [Italy government saying Germany should leave Euro]

The short answer is yes.

But the long answer is more interesting. With Brexit, the analogy that the UK is deciding to leave a club has often been used. The same analogy can be applied here: Can (or should) a club be able to evict one of its members? The EU does have a mechanism to punish unruly members by fines/withholding funds, but as far as I have been able to see so far, no means to evict a member. If that does not exist, it does seem to me to be a change in powers that is worth considering. But in practice it would be incredibly disruptive, especially for a Eurozone member, and introducing such a mechanism would need to be agreed by all the member countries. That would mean each would have to weigh up the benefits of being able to evict someone else against the impact if they were evicted themselves. I would expect such a proposed change would be rejected because of that.
