[WS:] Who decides what "the purpose" of something is - some armchair academic? Everything in this world serves multiple purposes, depending on who is using it. Capital owners certainly want to use the state to the purpose you stated, others use it for protection, production of public goods, income distribution, collective defense etc. To what extent each of these purposes is being served at the expense of other depends on the power relations - of course - but the claim that the state serves a singular purpose of being the executive committee of the bourgeoisie cannot be taken seriously. Not only that - it is counterproductive to the interests of the working class, although it may fit the mindset of petty bourgeois academics and self-styled anarchists.
