I think I'm the typical person you're inviting to say it and I will: those are acceptable losses. Whenever you want a new licensing scheme, you have to balance the gains with the losses.

For example, my city had an issue where donation boxes would pop up on city lots next to parks and become dumpsters. The city implemented a licensing scheme, which forced the companies and non-profits to collect from the boxes at a regular frequency, and now the problem is solved. No bags of old books left soaking in the rain turning into useless pulp. But someone could argue the licensing scheme stops some non-profits from collecting much needed donations. It totally does, but it's worth it.
