You have to have them to balance the radiator
otherwise all the hot water goes to the first radiator and it's red hot, and the others in your house are stone cold.

I haven't taken apart the central heating in my flat
but I can categorically say that I have one boiler, three rads on a linear circuit, a centrally controlled thermostat in the sitting room and not a blessed thing on any of the radiators save the drainage valve on the one by the front door.

Also, to the best of my knowledge
the water isn't static, it gets pumped around the system so while the rads at the end of the system may be cold until the water gets to it, it shouldn't be forever unless you've got a blockage.

You clearly don't understand how heating systems work
