But I am guessing here.
> cutting stuff in the garden
Wait, are you talking about like using a Ninja sword as a gardening tool?
Or do you mean something like playing Fruit Ninja IRL in your backyard, chopping up watermelons and other fruits being thrown around in the air, for fun?
You have to understand that as a headline factory. The Offensive Weapons Act already prohibits carrying anything with the intent of using it as a weapon. Police routinely confiscate kitchen knives from the pockets of young men in stop-and-search. The specific bans on specific weapons are part of a stupid media cycle where a crime is carried out using a fancy weapon so the government legislates against that specific weapon. It's like trying to outlaw cryptocurrencies by banning them by name one at a time. It's incredibly stupid but a tradition of UK politics because it's easier than trying to untangle the actual problems of knife crime.
It's also a UK thing, not an EU thing. There isn't an EU level knife directive, rules vary; Czechia and Finland seem to be loosest from some brief googling.
I'm not either pro or against such bans because I'm not well versed into the crypto universe (just like almost anyone else) though
The governments, being useless and focusing on the wrong things, are banning objectively non-nefarious objects (ninja swords, anonymous coins) that can be use for good by good actors (cutting stuff in the garden, sending money in privacy) but are sometimes used for evil by bad actors (murder, money laundering), like many other things.
How can rape and murder ever be used for good by the general public? Did you ever meet someone in need of a legit rape/murder in the name of good? How can you possibly make such a comparison? Honestly!
Banning a tool doesn't stop the criminals from committing crimes that are already illegal, it's just removing a tool from the law abiding citizen.
