and a coin with 1mb blocks forever has economic viability?
Things need to evolve with real life technology. Not with forced manipulation of the system. Because you need to respect the rules of Nature and its nature of self regulating!

If higher fees are needed, I'm good with that! It will encourage the smaller node people to invest more in hardware and spread as a business model. Also it will evolve naturally to bigger blocks as the price rises too much and the use of the coin is too extensive!
(edit: because they don't want people to migrate to other coins
)
