Are you likening the UK to Russia?

This is not a fictive fine, it's threats of imprisonment, and ignoring the whole thing means having to avoid travelling to or through the UK for life, and that's assuming the UK doesn't try to activate any sort of extradition agreements.

Even without going to prison, that's a permanent and quite significant theft of freedom of movement. If you ever travel abroad, you could end up accidentally booking a transfer through the UK.

No one ends up unintentionally transferring through Russia anytime soon. And likening the legal threats of a foreign nation to a joke from your neighbor makes no sense.
