It won't happen. Commercial sellers will always want the kind of 'footfall' (clickfall?) that a site the size of eBay gives. Private sellers can choose to sell locally cash-on-collection, on ebay, facebook, local sales, or wherever, and remove the risk of comebacks...but you can't beat the sort of prices you can get on ebay, especially for rare and sought-after items, partly
because people know they aren't risking buying tat from a shady seller, and partly because you have an entire planet of potential buyers in front of you, instead of whoever turned up to your yard sale.
The best you can do as a private seller is either protect yourself by using tracked insured delivery and documenting the item well, or take the hit of the occasional 'lost' item. On the whole though, most people are still honest, and I personally have found at least 99/100 sales have gone smoothly, so it boils down to an extra 1% in costs for me in the end...
