Well sure, that's easy for you to say, but you have a salary :) Other
developers may find the incremental benefits of decentralisation low vs
adding additional features, for instance, and who is to say they are wrong?

It does add something though! It means, amongst other things, I can switch
of all my servers, walk away for good, discard this Mike Hearn pseudonym I
invented for Bitcoin and the app will still work :) Surely that is an
important part of being decentralised?

It also means that as the underlying protocol evolves over time, getutxos
can evolve along side it. P2P protocol gets encrypted/authenticated? Great,
one more additional bit of security. If one day miners commit to UTXO sets,
great, one more additional bit of security. When we start including input
values in the signature hash, great ... one more step up in security.

Anyway, I didn't really want to reopen this debate. I just point out that
third party services are quite happy to provide whatever developers need to
build great apps, even if doing so fails to meet some kind of perfect
cryptographic ideal. And that's why they're winning devs.

Now back to your regularly scheduled block size debates ...
