No need to apologize for your question! We're all here to learn.
For every question asked, there are many lurkers wondering similar things.
Some food for thought on point 1:
Illegal drugs are already banned in most places; did these commodities become more or less valuable after such bans?
There is a good discussion between Stefan Molyneux and a caller to FreeDomainRadio here: https://www.youtube.com/watch?v=G6UVQUjS1T8 (warning - video has a not-safe-for-work title but the content is audio-only and is not offensive)
Since bitcoin itself is a currency, as infrastructure and networks and cryptoeconomies evolve, shouldn't the need for conversion into fiat diminish anyway?
The question really hinges on timelines. In the short term, large bans would have an effect but they would also create competitive opportunities for other countries. Lots of venture capital is flowing into cryptocurrency right now. Governments all want a taste of that, so they are necessarily hesitant to use the ban hammer.

Bitcoin works because of Satoshi's foundational discovery/contribution/invention in computer science that allows for a distributed, decentralized, public ledger. All transactions are publicly visible but to tie a transaction to a person, you must also tie an address to a person. The entry for a transaction in the blockchain will show bitcoin addresses but not your name or other identifying information. If someone looks at your computer and sees that you control a certain address, they can then do some blockchain forensics to see with whom you have been transacting. Interestingly, it is trivial to create a new address for every transaction and many services do this automatically. Additionally, services like CoinJoin obscure ownership by 'mixing' coins. Projects like Dark Wallet are working on integrating this sort of coin mixing into normal wallet operations.
2Your two questions should be asked in two separate posts. But I believe similar questions have been asked before, so please do a search as well. – Nate Eldredge – 2014-05-09T01:01:27.943
1Since the two questions were not related, I edited your question to remove the second question. Please ask it as a separate question instead, so we can focus on one topic in each question. You can find the original text in the edit history. - I also think that Nate is right and both of your questions already have answers here, but unfortunately I don't have time to look for them right now. – Murch – 2014-05-09T08:49:58.760
