The first point has nothing to do with bitcoin. Any internet entrepreneur has to consider that question at some point and the answer is mostly: no, I do not need to learn all the laws of all the countries before starting a business online. I sell a service online. I know that I do not need to transfer VAT to the US government when selling to American citizens. I know I need to transfer VAT to my EU government for any sale to a citizen of an EU country. So far so good. Do you honestly think I know what to do when a Kenyan or Vietnamese citizen makes a purchase? Do you think most small US-based companies transfer VAT to the EU? Do you think anyone bars citizens from countries they don't want to deal with from purchasing their services? The internet is still the wild west for many things, because governments of the world still haven't caught up with internet commerce. Nobody, except for the larges companies, can reasonably be expected to be able to deal with the laws of a few hundred countries.
