Unless your backup is not visible to the virus, you are toast. This is a situation where unattached, or off-site backups and cloud solutions win. A simple user with an always attached USB drive will still be toast.
Bitcoin comes with an implicit political agenda attached
Whose?
Libertarians love it because it pushes the same buttons as their gold fetish and it doesn't look like a "Fiat currency".
One, any currency is a fiat currency. People have to agree to use it, be it beads, dollars, bitcoins or polished turds. Just because you have a problem with libertarian views (I do on some), does not mean an insulting argument is valid or appropriate
Mining BtC has a carbon footprint from hell as they get more computationally expensive to generate, electricity consumption soars;
Printing and minintg currency has a big carbon/environmental footprint as well.
Bitcoin mining software is now being distributed as malware because using someone else's computer to mine BitCoins is easier than buying a farm of your own mining hardware;
It is always easier to steal someones wallet than work for it. There will always be those that try to do just that. Your point?
Bitcoin's utter lack of regulation permits really hideous markets to emerge, in commodities like assassination and drugs and child pornography;
This one really gets my goat. These markets (whether hideous or not), exist already, regardless of the currency. It doesn't matter if you by crack with blowjobs or acid with BTC, the market is there.
and finally Bitcoin is inherently damaging to the fabric of civil society because it is pretty much designed for tax evasion. "BitCoin looks like it was designed as a weapon intended to damage central banking and money issuing banks, with a Libertarian political agenda in mind—to damage states ability to collect tax and monitor their citizens financial transactions," concludes Stross.
The blockchain is public. Once a wallet is tied to an individual, all its transactions are public, be they income that is untaxed or 'hideous market' purchases. Even years down the road, if a wallet I used to buy ecstasy in 2012 is tied to me in 2042, that purchase is now and forever tied to me (as well as all other transactions done with that wallet).

Not to be mean, but it is often true, and is in the case of family I help out. That is why I answered the way I did.
People who go to conferences are the ones who shouldn't.
