>You have to acknowledge it, and then a) provide some form of solution (kinda contradicts its principles) or b) argue that it isn't as important compared to potential benefits of Bitcoin.

There is no solution to the specific problem of electronic cash making it easier to transfer money in exchange for an immoral product like child pornography, just like there's no solution to the specific problem of strong cryptography and the internet making it easier to disseminate child pornography.

I would argue, with plenty of rationale and evidence, that the economic freedom provided by these technologies, has the potential to massively improve the quality of life of the world's population, despite these unavoidable side effects.

If there were fewer poor and desperate families, there would be fewer parents who sell their children into the sex trade. Economic freedom facilitated by technologies that also make it harder for states to prevent trade in immoral goods reduces the number of desperate parents and we can reasonably assume reduces the problem of child exploitation as a result.
