Of course it's hyperbole.
Too many posters on the other thread pointing out boring things such as this is the maximum sentence for repeat offenders, for the specific offence of lying on your location form (so travelling from a non-quarantine country and saying you had been there for the previous 10 days, but that being a lie because you'd arrived there only 48 hours before from a quarantine country)
We need effective and well respected quarantine regimes. We don't know where the next variant will appear, but once it does emerge, we might want to seal down against it quickly and effectively.
The consequences - vaccine-escaping new variant in circulation could cost many lives and plunge us into another lockdown.
