The problem with taxing consumption is that it's pretty regressive. Not to say that there aren't solutions, but the existing sales tax, gas tax, etc aren't it.
Taxing income is also regressive because most rich people have trust funds (and pay a flat 15% tax) or push luxury purchases under the guise of business expenses (and pay no tax).
Taxing consumption instead of investments and savings seems like it would guide society more towards saving and investment instead of short-term consumption, though, no? Personally I'd rather not have taxes at all, but if you forced me to pick on of the three I'd pick consumption every time.
It’s funny how anti government people tend to like socialised roads, police and military, but the socialised education and housing.
Really depends on the person. I'm for privatizing all those things. No public spending on education, housing, roads, police, or military. Minarchists tend to prefer some services while anarchists may not want any government at all, thus no government expenditures.
