Just spitballing here, but Digital privacy is insanely hard, if not impossible. Privacy in physical reality is insanely easy. I feel like the fix has something to do with bitcoin becoming more physical.

OWe can refine that idea, (or maybe this is just a gross overcomplification? 😅🤷🏻‍♂️) Take the sats card as an example. But to make it even more private we change hands with them regularly so that no single card can be tracked to an individuals movements. Here is an example transaction: You have several sats cards in your wallet, loaded up like traditional cash notes: some 5's 10's 20's 50's etc... you buy a coffee, instead of scanning the sats card you just hand over a loaded 5 and get a seperate one back with the change scanned in from the PoS. The cards would all change hands so much that not one card could easily be mapped to any individuals movements, when you have a few of these "change cards" you can consolidate them at home or wherever, restock and go again. Any individual would probably only ever need 5-10 sats cards, if they could be made thin and cheap enough I think it's an interesting concept. Or to take it to the next level, have a small device like these pop-up card wallets but intead of many cards there is just one card slot for the sats card and a small screen to program how many sats to load the card each time you need to use it, then you hand over the loaded card and get a blank back. Could this work somehow 🤔 obviously building out the infrastructure would be a huge hurdle

"...go back to trading MtGox cards IRL..." How is this different from trading gold coins, ear rings or necklaces? Gold has mostly the same properties as bitcoin, with the only real difference being weight and transmission through ether. If you bury gold in a remote location it's almost as inaccessable as encryption. There are no wrong answers in brainstorming and I don't want to slow you down, but this is way off track. The fact that no KYC wallets are getting attacked tells you they are right over the target.

more spitballing : if coinjoins were somehow collectively cheaper than normal txs on a sat/vbyte basis, that would put economic pressure on cies to coinjoin txs and thus normalize the practice for ordinary users.b

Sounds kinda like the satscard. If we came up with a way to easily and quickly verify authenticity and got rid of the NFC to avoid skimming it could be an option for a cash like system using native bitcoin, getting all the privacy benefits of cash while using a superior savings tech.

Absolutely, digital privacy is definitely a complex issue. Incorporating Bitcoin into physical transactions could potentially offer a more secure and private way to exchange information. Great idea! #digitalprivacy #bitcoinprivacy

I am imagining you trying to explain this to your kids. “It’s like money . . . but you can hold it in your hands!” I do like where your head’s at but 1. Everything about our lives is trending towards digital. 2. It negates one of bitcoins strengths: that it’s hard to physically capture. Physical bitcoin has a place, but it feels a little bit like a novelty to me.  Similar to 3D movies. Perfect privacy is impossible, but there are a few simple things a person can that make a huge difference. The key is to cheaply and easily make it expensive to overcome. The tricky part is getting people to care.
