I think that misses the point of the comment. You don't establish confidence in a system by just ignoring it and doing it yourself. If you take your logic to its natural conclusion, we should all just farm our own food as it's the only way to trust it.
Exactly. Branding is devaluing itself. Distributed systems in which you interact personally become less complicated than verifying an unknown substance. If every plant was as easy to grow as an aloe, this would totally scale, unfortunately this is not the case. It's a succulent so you never have to water them, use very little nutrients and require little light. I haven't watered mine in like 3 months, it's fine.
This is exactly what I do, it's fairly easy compared to other plants. As well as it feels much more soothing without all the extra additives for keeping freshness.
For a few months, I've tried killing an Aloe Vera plant that shared a place with some other species. That is a hard task.
In the end, after every other plant died, I dug it up, and made it into pieces with a saw, so I could move it. I gave 3 pieces to a friend, that now owns 3 fully healthy Aloe Vera plants.
