I don't see any wrong if the government want to support unemployments considering anyone need food to live, otherwise they will scam or steal money.
Taking advantages of decentralized because you don't want to pay tax isn't cool, but I can't blame since it's your choice.
Actually Satoshi didn't want to make a decentralized world, but he just create a payment tool that can be accepted widely and can't be blocked because of decentralization.
It would not be taking advantage of the system, it would be the system 😊 Plus it would be a Paretum optimum : total utility is maximized when everybody maximizes his own utility.
Ok Im joking with using extremes but it makes sense
