I largely agree, but there is an argument that in SA, with out legacy of apartheid spatial planning (the working poor live on the outskirts, a liong and expesnsive commute away from where the work is), public transport is a public good.

Marianne Merten in another piece tries to suggest that electricity is a public good - THAT I totally disagree with (neither is LP gas, nor petrol, nor diesel a public good!)
