In a free society, without any welfare state, the role of voluntary organizations who try to help the poor and needy - like the church - will likely be bigger than under statist conditions. It is very probable that of all voluntary organizations who are helping the poor and needy the religious organizations have the best changes in competition with, for example, former socialist groups who possibly become less motivated if they can't spend no tax money anymore and have to compete with people with (fanatic) faith.
If we look at history we can see that the church has flourished more while there was less statism (Ireland, Friesland and the highly decentralized Germany and Northern Italy in the Middle Ages for example). And while the state was big (the years after the French revolution, the Italian unification, the German unification, communist Eastern Europe, the social-democrat western world after World War I), the church was weak. The advocates of statism have always been fighting the church. Examples: massmurder of clerics and openly catholics after the French revolution, Kulturkampf in unified Germany, suppression of the church and even the killing of priests in Poland - and Eastern Europe in general - during the communist era, anti-christian views spread by the (cultural-)marxists in Western-Europe.
I really don't know what the age of information has to do with the survival of an entity like the catholic church. That is like an assertion that choosing voluntary for being a member of the catholic church has to do with (a lack of) information, or a lack of rationality. I think that the attraction of voluntary organisations like the catholic church has to do with the lack of giving meaning and a lack of a spiritual component atheism has ''to offer''.
I think it would be good to see where someones priority is. Striving to destroy the state or religion. Destroying them both would not happen. As long that atheists have no satisfactory answers to the big existential questions religion will continue to exist. Whether you will like it or not, whether you think all religion and all religious views are fiddlesticks or not, i think that religion is here to stay. As long people have the urge to transcend from misery, suffering, mental pain, unsolvable solipsism, lack of love, agony and the abyss of eternal death and entropy, and the rationalizations - adjurations of escapism - (''What do you lose? Come from nothing go back to nothing.'' /''Be glad that life has no meaning'' ''/You have to give a meaning to the moments''/ ''We all gonna die''/''It is ridicule to seek a meaning of live outside live itself''/ ''He lives on in his music/writings/children [or in our thoughts]" /''Where death is i am not and where i am there is no death etc. etc.) some atheists come up with are held for what they are there will be a market for religion. And i suppose that even such a simple thing like pangs of love will continue to exist as long there is time-space and human life, even under conditions of an extreme rational society, with long life, the best painkillers, holodecks and horns of plenty.
Conclusion: Religion is here to stay. As long there is time-space and human life, there will be religion. If the highest priority for someone is to crush all religion, he should support the state, because less statism means more church. I have given the example of voluntary organizations helping the poor and some historical examples. Secondly: the lasting attraction to religion lies not in a lack of information or rationality but in the offering of meaning of life. "Accept what you call love is just a bunch of chemicals in your brain and there is no afterlife" has - no matter if it is true or false - less attraction to people who seek a meaning of life than God who is love and eternal life (no matter if that is true or false). If you look in the abyss, the abyss will look in you. So confronted with the ultimately meaninglessness of life (you die and all matter will face a big chill or a big crunch) you can ignore the fact, you can use some rationalizations as stopgaps, you can start drinking or using drugs or you can find a non-rational way out. All of these methods, including the methods atheists have, after being confronted with agony every day are a form of escapism.
I know that Stephan Molyneux (and people attracted to his ideas) is vehemently anti-religious. This topic is not to provoke others to ridicule religion nor to let them expose arguments against religion, but to give some rational arguments why religion will be attractive forever, why religion will not disappear and how weak and unconsoling the ideas are where non-religieus people come up with while facing, for example, the prospect of total annihilation.
