Also, I call bullshit. People want Bitcoin because of it's unique properties which are possible thanks to decentralization. Who gives a fuck about sending a few micro transactions for free when governments worldwide are preventing people from using (or even continuing to own) their own fucking money?
You, like all of the core supporters, keep conveniently ignoring decentralization threats related to forcing users off the main chain, and only focus on node cost. I understand you hold the position of 'keep the coffee money off-chain and lets use the main chain for big stuff', but what good is having sound money if you can only use it for big stuff and not for every day things? Why should I need anyone's permission to transact? There's also huge privacy concerns with allowing the government to see all of your small transactions, as well as the taint issues for your bigger purchases even if done on chain.
I say there doesn't have to be this false dichotomy. Bitcoin can handle everything on chain. I would like to see your kitchen table math on why you think 'datacenters' are going to be needed any time soon, even for much larger blocks.
Most importantly, in the long run I don't think the security model will work well with only large transactions being done on chain. There won't be enough fee revenue, security will drop, and people will simply use other coins that offer both high security and low fees.
