Been mulling this over recently: 

Are blockchains only a valuable/viable technical solution when credible neutrality matters?

No. Use cases like helium don’t require credible neutrality of L1

Perhaps a more interesting question is: “are use cases where credible neutrality is the most important thing the most compelling to be solved by blockchain” (eg is credible neutrality the most imp/interesting property of blockchains)?

Ya, CN def. has overlap with the other properties you listed

Gonna keep thinking abt this one. Maybe my aperture is too narrow, but as I think thru the use cases (finance/DeFi, governance/voting, digital ownership) that get me MOST excited about blockchain, they all revolve at their core around CN (vs. the other ones)

i think the key properties are

credible neutrality
censorship resistance
programmability
composability
micropayments
regulatory arbitrage

probably CN is the most broad and therefore most important, but hard to compare these concepts IMO
