Why dont they just..?
Answers:
Because then money would have no value.
It currently has value, because to issue it you have to have assets (usually gold) of that value. That's why Bank Of England notes say "I promise to pay the bearer on demand the sum of ."
The notes aren't the money - the gold in the Bank of England's vaults is the money, and the notes are a representation.
If they printed more notes (or minted more coins) the value of the gold wouldn't increase, so in the global markets the value of each £1 would decrease.
It has been done - various governments have "devalued" their currencies at one time or another - but its a big compromise to make, and only ever done in a real crisis.
Inflation
gosh it's not that simple. I don't understand all the complexities of money but I know they have know how much money is in circulation so that everything is fair and square so to speak.
That's why they break up money launderers; not to stop there fun because then everything would go down in value because of the extra money on the market.
