The presumption would be the underwriting risk is batched and pushed to one point (the exchange point). It's economically feasible to underwrite a single transaction for hundreds of dollars to buy Bitcoin (exchanges doing AML/KYC). It's much more uneconomical to underwrite a $0.001 payment -- as a result building a real marketplace for this becomes difficult even if there would be a lot of users.

I don´t get this answer. Linden needs not underwrite any micropayment inside it´s silo?

The only utility in LN is hopefully retaining decentralized properties of bitcoin. PokerStars, Linden & WoW have supported micropayments for a long time?

Im not sure why any of these services could not grow 10x and still function internally? They are already servicing tens of millions.

I think you're missing the point. You can't scale Linden's micropayment worldwide without there being counterparty risk. It's much more useful to build these on top of decentralized systems with a strong bedrock without fearing the company being targeted by hackers or governments. Can you use Linden in China?
