A quick check at amazon shows these costing about $14 each, no doubt much less in bulk but still expensive. Perhaps inquire with the shipper if they would accept them for reuse if cleaned. If the shipper is friendly they might consider setting up a program to collect these from your city and return them for reuse. The shipper could save considerably on costs and you might have found a new business.
Your very long comment reveals that you understand the analogy but would rather complain about it than address it. Russia invaded Ukraine and is killing it's people, correct?

It's not an academic pursuit or a fun problem to study, it's "I've got tanks and disposable people, I'm taking your land".
He (or you) ascribes alot of nuance and careful consideration to someone who has demonstrated nothing but malice and avarice. Putin clearly cares nothing for both the people of Ukraine and his own people. Why are we trying so hard to be understanding to a murderous dictator?
I know I'm going to get downvoted but I use FSD every day. It's not perfect but it keeps getting better, and it's already the best solution out there. If you haven't actually used it then all you have is someone else's opinion.
