"Simple" doesn't come in to it when airport management are faced with a 5-figure bill for hardware, installation, commissioning, SRG approval, ongoing maintenance & support etc. Unless you are called Jeremy Corbyn, contrary to popular opinion there's no magic money tree growing on any airfield in the British Isles (most of us would love those to exist as it would solve innumerable problems in life). Great kit, and I totally understand and support your wishes, but as said previously someone has to pay for it. Anyone fancy a whip-round?
