If bitcoin is going to scale to the moon we need all these options, we need bigger blocks and the lightning network and Xapo and Coinbase.
It can be argued that lightning network developers have an agenda to keep blocksize small in order to increase lightning network usage, don't know if true, but seems plausible.
Agree, just like we have commercial banks, land banks, saving banks, retail banks, credit unions, building societies etc.... All perform essentially the same service but on different levels yet all tie back into the financial system.
So agree, we can do with these networks as long as they all tie back into the blockchain.
