On P2P payments from their FAQ: "While the payment appears to be directly between wallets, technically the operation is intermediated by the payment service provider which will typically be legally required to identify the recipient of the funds before allowing the transaction to complete."
How about, no? How about me paying €50 to my friend for fixing my bike doesn’t need to be intermediated, KYCed, and blocked if they don't approve of it or know who the recipient is? How about it’s none of the government’s business how I split the bill at dinner with friends? This level of surveillance is madness, especially coming from an app that touts "privacy" as a feature.
GNU Taler is a trojan horse to enable CBDC adoption. They are the friendly face to an absolutely terrifying level of government control in our lives funded by the same government that tries every year to implement chat control. Imagine your least favourite political party gaining power. Now imagine they can see and control every transaction you make. No thanks.
Your first example is tax fraud if you hide it
Edit: it looks like you edited your post to state the guy repairing your bike is "your friend".
Noone is going to go after him if he just fixes your bike. But if he fixes the bike of his 1000 friends each month, they will go after him if he didn't declare it.
That may technically be true, but it's currently very normalized. Do we actually want to denormalize it? Should the government know about every trivial transaction?
For small sum in-person payments, regular cash is still the best option and will continue to be so, GNU Taler or not.
There is a middle ground. Cash has a physical trace but it isn't known by the government right away. We need digital cash that actually functions like cash.
not if they're only covering the cost of parts
