The attachment to cash is something I’ll never understand.

It’s easy - tax evasion, money laundering, secret financing of things you wouldn’t want others to know. All perfectly fine reasons to fight for.

Cashless society is a controlled society. While some may misuse cash for illicit activities, many prefer it to protect privacy, maintain personal control, or avoid digital vulnerabilities. Dismissing cash usage solely for nefarious reasons overlooks legitimate concerns and individual freedoms, and equates privacy with wrongdoing, a perspective that might inadvertently erode fundamental rights and personal autonomy.

This is all technically true but cash is not the answer.

Right now there are so many easily accessible ways for governments to spy on people (cell phone geolocation, call metadata monitoring) that I’m not sure that for the purposes you think of you aren’t screwed already anyway. From this perspective fight for cash use becomes a bit theoretical.

The only people that I know of personally that are strongly for cash are either people that frequently skirt around taxes (“minor” stuff like car repair shops) and unfortunately conspiracy nuts. Genuine privacy oriented people exist but realistically the majority will be there for selfish reasons.

The societal cost of tax evasion, money laundering and financing organisations that legally require transparency (political orgs, NGOs etc) are massive and immediate.

What we really need is strong oversight of institutions, government transparency, rule of law and healthy democracy. Those are the things you want to enshrine in your constitution.
