While giving those who don't want to use them the burden of having to put this into their house rules, convince the other players, and -if it is a player having this view- the GM
To be fair, if the DM insists on using material components then the player either has to accept that or decide not to play.
I agree in principle that a more generic rule set that nonetheless provides the option of MCs would make for a better, general purpose (and, dare I say it, modular) system. But it's also true that adding them to the main text, with a sidebar saying "ignore them if you want", is arguably better, from a purely practical point of view.
