"The government has collected an extra $20m, but shareholders have collectively lost $200m in the value of their asset!"
T4P, I may have misread your post but you seem to have only included 1 year worth of tax revenue, over say a 10 year mine life wouldnt $200m be collected for the same 200m market cap loss? over 20 years 400m tax collected for 200m market cap loss etc etc
"And...who owns these roads, rail lines, ports, etc...when the resources are gone?"
When the resources are gone there will be no need for the rail and ports as noone will be using them! lol. I am for the tax to fund / encourage non mining industry in Australia. This needs to be done now for the time when the quarry runs dry.
