Simply wishful thinking»
People will pay in BTC only merchants that they already trust. Think high-reputation businesses like Amazon, Costco. Do you really think companies like that would start being dishonest if they accepted bitcoins?
«compared to one that requires brand new hardware»
No, accepting Bitcoin doesn't require new hardware. It's a software update to a website or to a point-of-sale.
«You also ignored -- probably because it is in your interest to ignore it -- that the reason merchants have no incentive to adopt is that nobody uses it»
You can continue writing they have "no incentive" but it doesn't make it true. This is the 3rd time you ignore it, and the 3rd time I point it out: their #1 incentive to accept BTC is to avoid chargeback fraud. Will I have to repeat it a 4th time?
As to "nobody uses it", I am not ignoring you, it is simply that you are wrong. Usage is growing: we got from 0 to 160,000 merchants in a few years, the transaction rate is doubling every 18 months (not due to speculation: https://news.ycombinator.com/item?id=15281860)
«Bitcoin as it stands is a major regression in consumer benefits»
It is a (small) regression, yes, no denying that, but it is far outweighed by the advantages: permissionless, near-instant international payments, no inflation, censorship-resistant, gives access to the underbanked/unbanked, etc.
As to Apple P2P, it is pointless to continue discussing it before it is rolled out and before we have a clear idea of its advantages and inconvenients. But I maintain my position that, if not delays, there will be transactions limits, and it also won't ever be used widely (for starters, only 2-3% of the world population has an iPhone.)
