Since we have a tendency to get sidetracked, my position is this:
- Cash serves a vital function for people who haven't been able to adopt other payment methods. That is a time limited factor. In 20 years it will be a very different situation.
- Cash serves a vital function for people who need to be under the radar on some level. That's probably my main concern. I don't think either the current government or Starmer give the slightest shit about that side. I'm not sure any government can be trusted to implement an alternative.
- Adoption of non-cash payment methods is very, very high and growing. This is not a value judgement, it is an observation.
- No government is going to regulate to force businesses to take cash... Or at least it's possible they might for supermarkets, as these are a pretty easy to define category in law, though there is no indication that they will.
- Cash is not a panacea. It has utility in some specific situations, but it won't stop supermarkets implementing reward cards or a government suspending your bank account or surveilling you.
Cash is an expensive system to administrate. It requires a lot of infrastructure, and has a lot of loss and vulnerabilities in its distribution and use. It is therefore not in a great position with cost cutting by government/companies as it is. Individual action will not, I think, make the slightest difference to this situation.
On 'advocacy' I think what a lot of us are trying to say is that, despite the fact we're not exactly comfortable with the potential loss of cash, we are finding ourselves using cashless because it has just become a bit ridiculous not doing that.
