7,000 bn divided by 60 million = £116,666 per head of the population not £225,000
============
Just so you can re do the maths, there are 30 million tax payers in the UK

So if you were to be charged £1 at the ATM, you would have to be withdrawing £2000. Or when you withdraw £20, it costs you 1p.

Lets make it a pound. That raises more money and that means more people can have their money redistributed.
It also makes it absolutely clear that the money is being taken.
If you tax the other things, then it isn't clear that the money is being taken, and in lots of cases its too late when people find out.
Look for example at Brown's tax raid on pension funds. That's taken well over 120 bn in present values from people's pensions. In addition because it has dropped returns on equities, the result is that share prices have dropped. Another 20% roughly. It's also part of the drive for debt and been a direct cause of companies gearing up and becoming more risky. All hidden away.
However, you seem to be claiming its a small effect, in which case it won't raise much money. However, people keep claiming it will raise a lot of money. Big inconsistency - big lie.
