You'll probably find that the go-around charge isn't there for go-arounds that are needed for safety reasons, but just there for people doing what you proposed to do. ie. take up room in the circuit, but avoid landing to avoid any charge.
The USA is different. They fund their airports differently. It's a simply fact that airports need to be paid for somehow.
In the USA they are paid for via taxation, in the UK, the user pays.
