UK TV license

I’ve been watching clips of people being harassed by agents trying to collect tv licence fees. Why on Earth are they pursing this archaic model in the current technological age. Most under 50s use the internet free netflix tech news android 9 for their media, and pensioners are exempt from the licence fee. Is it really worth harassing the entire population over something that could be designed intelligently? If they do insist on keeping the fee, upon paying send the account holder a pin to login to iplayer with rather than asking each time if you have a licence. Better still make iplayer subscription based. Money Would still only be taken from users and the rest of the population would stop being harassed. For the dying breed who use their tv for tv take a nominal sum out of general taxation.
