1) with 2MB (or 4MB), nothing changes much here
2) second layer (LN) does not even exist currently, so pointless to argue whether LN become decentralized or can be used only in centralized maner as seems today
It does actually. In a small amount of time you will have people asking for 6 or 8 MB, that's for sure. It is not pointless to argue about LN. LN is being designed so that it is decentralized, don't spread misinformation that it will be centralized when that is not the case.
So going to 2mb, as planned by core and classic, changes much. It will make people ask for 6 or 8 mb!
I disagree. (but core are planning 2mb anyway?)
(will "users" generally ask?, if they can transact ok, or mainly classic/unlimited supporter, who have a right to an opinion after all, and will be somewhat appeased. i concede, there will come a time when larger blocks are asked for, but that is a different story in a dynamic situation)
I want 2mb because it is achievable, is in the roadmap of core and classic, is the most obvious option, could easily cope with continued growth for the foreseeable, is not divisive or partisan, and I want to know there is a buffer for emergencies or rapid growth.
I dont want segwit, sorry. (i seem to be on my own on this?)
Core want segwit and 2mb. Big blockers?
I just want 2mb, before anything else. Before segwit.
