Etsy already does all that. Funds are held for some time. There's also a way to dispute a sale to get a refund and so on. Plus credit card charge backs if you're really pissed. Paypal basically exists because it's included htis functionality for the last 20 years so it's nothing new.

The thing is that the vast majority of buyers are perfectly happy with their drop shipped item.

That's the real difference, Darknet has very savvy buyers because the barrier to entry is fairly high and theres is little real competition. If you don't like Etsy then there's Ebay or Shopify stores or Amazon handmade or a local craft fair or just emailing a maker.

I think it's important in these situations, like many others, to not jump to a conclusion such as "legit marketplaces are idiots for not doing X" but rather "why doesn't X work for legit marketplaces but does work for non-legit ones."
