Marx, to be a qualified posek, one needs to spend years learning shas and poskim, not reading the Babylonian talmud for 45 minutes every day while drinking coffee .havei mesunim bedin, be diligent in paskenint – ine needs time, not an hour or two of perusing rishonim. One needs to have shimush. Kara veshana velo shemash is an am haaretz. Halacha requires a clear head, free of bias and foreign junk that one absorbs online, in the work place and through media consumption. It also requires a tremendous amount of yiras shomayim.
If someone is missing even one of these things, they cannot rule on any halacha shailos.
