Well this whole thread is regarding whether or not someone ought to vote for a non-conservative government. So the first thing you could do to avoid such a situation is vote to elect individuals who are true to their word and argue against policies that would rob you of all your wealth through taxation and inflation. Another step you might take is to promote a vision of society where we limit the government to a certain degree so that it does not acquire so much power that it can simply rob individual citizens without recourse.
Further, this particular question is whether the government legally ought to be able to tax without limits. You seem to be conflating that with if the government is able to tax without limits.
