It's unbelievable all the people that think they have the magical solution to "Bitcoin" when they could easily make an alt-coin with Seg-wit, unlimited blocks, etc. Look, if Satoshi wanted the Blocksize to be 2mb he would have made it that.
Bitcoin is supposed to be a digital store of value, not some micro-transaction dust coin.
This is a strange fallacy and I think it rose from the common description of Bitcoin as "digital gold" which definitely no one described it at the start of Bitcoin's creation.
Bitcoin was always supposed to be a currency. Satoshi would tell you that and he did, in the white paper for Bitcoin entitled "Bitcoin: A Peer To Peer Electronic Cash System". It really couldn't get much clearer than that.
What Satoshi also wanted was for Bitcoin's code to be open source, which it is, and for necessary modifications to be made to it, which they are. BU is not a good modification to make but if the majority of hashing power supports it that will be what rightfully changes the code and creates a new version.
