By encouraging tax evasion?

How did you arrive at that conclusion?

By 'cash' I mean funds in the bank, so 'cash' = cash and cards. Cash
available to use, means you can often get a 10% discount on a posted
price in a shop, especially true if they are offering interest free
credit on an item.

Cash available means you can spot a bargain and buy it if it is
something you want /need there and then, before bargain is bought by A
N Other. Cash means that if your washing machine dies and is not
economical to repair, you don't need to borrow money at high interest
rates to replace it, or go to the likes of that high street retailer
who let you pay twice as much for spreading the cost over a year or
two.

I mentioned nothing about tax evasion, or anything else illegal - just
simply not paying more than you need to for things.
