The tub is very realistically user reusable, at least once. Both the tub and the bag have less carbon footprint than a cotton bag, glass container, or metal tin. Likely less than transporting liquid detergent (though more than powder in cardboard)

The tub has to be thoroughly cleaned, and even then you shouldn't store food in it because of the detergents possibly permeating the plastic. I read this in an article about repurposing the tubs as Jack-o'-lanterns for Halloween. Anyways, what's your point? They could use cardboard just as easily. And that still doesn't excuse plastics being used today that are non recyclable.

My point is that cardboard is often not better than plastics. Especially if the priority is less carbon rather than concerns about [non methane or sludge producing] landfill usage.

Recycled cardboard has a higher (3x) energy footprint and water waste than pe products.

This is an interesting comparison. https://www.egglandsbest.com/exceptional-quality/sustainabil...

I don't see any way to steal electric car battery without actually stealing the car. Its big, heavy, scary (and actually dangerous), and highly integrated with the car

Unless the car is designed for fast battery swaps. It's still a big heavy item to steal, but it's conceivable to drop it on a skate and hoist it into a van.

i doubt this will be a big issue, the safety requirements around this will match the price of the damned things.

The $2000USD figure is approximately correct. We've run the numbers to be between $800-3200 depending on the weight of the battery, and how difficult it is to disassemble. 3200 for a 700kg Porsche Tycan battery. (My cofounder and I launched a company to disassemble the batteries robotically, if you're interested in helping us build it, please message me).

As an FYI there's no way to directly message capability here on HN so if you're interested in people being able to reach you you might want to put some form of contact info in your profile.

Sorry for that, I updated my profile with email.
