Definitely it will be difficult to implement at the moment. At the rate the government is passing legislation on tracking people and making companies provide their data to government whenever requested, though, I can definitely see one day (maybe 50 years) where all this will be possible. e.g. When cash is replaced by only bank accounts, then every transaction becomes traceable. As I said before though, you can as an alternative lower sales tax on basic goods and raise them on luxury ones.
