Do a sweep and see if it gets caught by the sweep detector they have built into one of those monero block explorers. Experiment with what those tools can detect. If I had a reason to be anonymous I would make sure I worked to understand how those free sweep detect tools work that charitable monero peeps have offered up to the public.

All objects on earth are a store of value.

Your friend may be right. But as long as he’s mentally stable he can handle loss and it might even do him some good long term depending on how old he is right now.

A better question is to ask how do we get a single farmer accepting and requesting monero usage.

The grocery store is a middle man that does little creation of value except occupying a location and marking up products to pay for electricity and labor, all of which must be paid in fiat by law.

Many farmers eek out a living off grid, and without any labor costs.
