A robust liquidation market does a lot to prevent waste, and it reduces the cost of living for those who participate, so finding ways to allow products to be truly sold as-is is vital, otherwise the next most logical option is to put those items in a landfill.
It's also important that there's no legislative hurdles to seelling items as-is, or there may be no legal way to sell a salvage products without completely overhauling them, which is usually not cost effective.
