Sure, but the premise here is that the population no longer trusts the government to serve their best interests, nor perhaps abide by the constitution. It's all about checks and balances. The second amendment gives some power to the people to revolt (in theory), as a check against government power. If the people need to trust the government not to do something unconstitutional (i.e. not confiscate weapons) for that to be effective, then the check is no longer useful and it defeats the purpose of the second amendment.
