as for the other part of the OP's scenario.. a NFC chip in someones arm..
well first:
they developed the NFC visa debit card 'touchless technology'
next its the NFC wristband. UK barclays is already developed this and will get people used to swiping their wrist across a machine.
https://www.shop.bpay.co.uk/categories/buy-bpay/product/wristband/wristbandso it is plausable that 'for convenience' people will opt for an implant so they never lose, drop, or have their 'wallet'(wristband) stolen/lost because it will always be available to them, implanted as oppose to worn.
Interesting.
Well maybe the chip implant in the head a little over the top. For example, what about a Bitcoin wrist implant? That would not be that bad.
Of course I would not use it, and I would insist for it to be optional.
But it's the content what matters, if the implant is used as a GPS tracking device ,so that disobedient people could be droned, then it's bad.
But if it's just like a Bitcoin wallet, that can be turned off anytime, then it may not be as bad as it sounds.
The only question it really boils down to is this:
Who has control over it? You or the government.
but lets see how people feel about bitcoin being twisted into the commercial LN system where the hub owner is the bankers getting their fee's to recoup their investments they handed to devs in 2014-2016
You know franky I used to think that you were a troll, but now I start to agree with you on certain point. Well maybe they are theoretical, and maybe I am a bit more open minded, but you do raise some good points to possible issues.
But you have to understand that everything now is experimental, all altcoins are like a giant laboratory, where certain things are tested. If Bitcoin tests it with LN, fine, I hope the DEVS will be cautious, like they have been before.
But if they fail, then Monero or Dash will pretty much take over, and their money would show up to be better alternative.
