1. Put the leaves from the neighbor's bags into an enclosed run with chickens and let them tear through them all winter. Downside is that they'll kind of compost and may not be as confetti-like as you want. Upside is that they'll be like compost.
2. Some people that put their leaves in bags collect them with a shredding mower or leaf vac. So when you wander around town looking for leaf bags, go for the dense, heavy ones since those will be the shredded leaves. Also check to make sure they have clover/dandelions/weeds in their lawn so that you know they don't do much weed and feeding.
I tell people, "I got into chickens for a really shitty reason - I wanted the manure for my garden." Most rescue chickens are too old to lay reliably and if you don't have a rooster, birth control won't be an issue. If you've got multiple paddocks to rotate them through, they will get many of their micro-nutrients while doing pest control for you. If you grow them some kale and toss a leaf or 2 to the ground every day or so (they seem disinclined to do self-service on kale from local experience), that will be a good source of calcium also. When they die of old age, they are a great addition to the middle of a compost heap which completes the circle of life. If you do get the odd egg you can choose to either compost it, or use it to barter with.
I will make the caveat that if we have the opportunity to RESCUE some chickens, this might be an option.
