Yes, because technically you would.
But its a bad example you quote picking a necessity of life and putting a quite ludicrous value on it.
Sorry but the points stand, there is nothing stopping you doing the same.
There is even probably no minimum amount you could offshore, so take £1 and move it to the Cayman islands and keep it there earning money away from UK taxation. The route is open to you. It may cost you a little more than £1 to move it, and in fees to look after your £1, but should you wish I bet you could. Now add ,000,000,000 to the end of the £1 and you can see why its probably worth doing for them but not you.
You dont have to be a rocket scientist to work out its not an especially good plan for the person with £1 but that for the other guy it makes more sense
