Not sure about Ethereum's equivalent, but 'Lightning' just reintroduces the problem of having one person act like a payment processor.

Not sure I follow.

		A node in the Lightning network (to simplify a lot) become the payment processor that would be targeted. (But it's kind of spurious- in practice, Coinbase, Block, etc. would be targeted far before someone running a Lightning node would be. The larger point is that very few people would interact with Bitcoin or other cryptocurrencies as a peer in the network.)
