The trouble with this argument is that even though belief is primarily created through material conditions, it is undialectical to assume it will not come back to influence the material world. In reality, the many cynical and idiosyncratic spiritualities cultivated by capitalism in its pursuit of profit have fathered bastard children with the political economy, which are churches, cults, and conspiracy mongers which exist parasitically by scamming and even threatening the proletariat, and it is wishful thinking to assume them to be immediately sublated after socialism is established. Just like with the exclusively material remnants of the bourgeoisie, battle will have to be waged against them until all of their dangerous elements have been removed or until they have been organically supplanted by honest, socially benign forms of spirituality in their entirety.

For instance, the Catholic church has been very much a material force fighting strongly against progress to the point where it openly backed fascist governments in Germany, Italy and Spain, and influenced the Polish counterrevolution. Obviously this cannot mean we could prohibit actual believers to practice such a faith; but we must without compensation strip the churches of all the political privileges and material assets they have acquired and enjoyed under bourgeois and feudal rule and which go much beyond allowing for the freedom of worship and congregation, and we have to severely punish any officials who put their faith above the state; if not in the interest of believers whose faiths do not at present enjoy equal legal status, then at least in the interest of those who suffer most from such a colossal waste of resources.
