Being programmable is the beauty behind Bitcoin. Without Script, sidechains and Layer 2 solutions would not be possible, and the system wouldn't be able to scale. And not only that. Nearly every change would require a hardfork. Being programmable provides the flexibility to support the creation of solutions that have yet to be conceived.

satoshis quote is not about other networks nor abandoning bitcoin due to fee increases. nor about saying fee's need to be higher. nor that a transaction should be 4mb large(the stuff your cultish scripts think should be allowed and prioritised)
its actually about different ways people can do things ON BITCOIN to benefit payments on bitcoin.. not arbitrary crap. satoshi actually cared about transaction leanness and transaction count potentials and scaling BITCOIN
you keep talking about getting people to avoid using bitcoin by using other networks which YOU stupidly call "scaling bitcoin"
(much like saying 'lets scale visa by getting people to use mastercard and pretend its just like visa' thus tell people it is visa)
you think increasing transaction counts on the bitcoin network can only happen as a huge leap so should never happen and be told to not even discuss incremental growth strategies..
you are trying to avoid any and all discussion of true bitcoin scaling and its obvious who you got your idea's from. and it was not satoshi
oh and your quote is actually about satoshi allowing transaction format futurisation via newest nodes understanding the new scripts to verify them, yet the core devs abuse that scripting mechanism to throw in new features before/without nodes even coming to a true consensus of readiness to actually verify the data and instead are FOOLED(not full) into pretending it verifies all data when instead is just bypasses it by assuming data is valid
anyways..
back t this topic. mempools data allocation of 300mb-500mb shows nodes can handle many more transactions than the limit you wish to hinder bitcoin to.. just to promote fee raises which are done just to promote your other network preference strategy
