Please tell me what do you think will happen IF If in 8 years we have negative growth but a 2mb or even 8mb blocksize?
Will transaction fees alone be enough to secure the network?
Will miners process torrents of spam for dust?
Will our network be stronger or weaker?
Are you willing to risk everything on unfounded assumption will continue to grow?
Peter R has already made a strong case that a fee market exists
without the blocksize limit.
We all know that fees become more important as the subsidies diminish
but that in no way means that we'll get more TOTAL fees by reducing the supply
of transactions. Quite possibly it would do the opposite.
