As you can see dear OP, people want to buy very different goods. So why not make a marketplace where anyone can spend and earn btc (and maybe altcoins) by buying/selling their own goods instead of a shop?
Just an idea.
Also I would like to see delivery services which accept bitcoin.
There are already multiple platforms offering this but delivery would be a great thing.
There are lots of such listing platforms. What they do is just list the products and give leads to the service provider. What they need is deliver the product with time constraints. Already platform similar to bitpay are doing intermediary work by providing fiat to the company and accepting bitcoin.
