The average number of inputs per transaction is around 2, so we must halve the rate. There's interesting ways to increase the block size, if miners really get mad, they could prevent some of this stuff from happening. For example, if Bob can produce to Alice some input R where R is some random data that Bob generates, with input R from hash H within 3 days, then Alice will pay Bob.1 BTC. Others might find that it is good enough for what they need in the short term (a particular transaction, day trading, etc) and not care what happens in the long term. Alice wants to pay Carol, she can't, because it's Carol's money in the channel with the Carol-Bob channel, so Bob can't credibly push that back to Carol.
