Capital Gains Tax

[CJ]

But capital gained is treated as income and taxed already for many property investors.

but not all. And most pretend they long term holders rather than traders. elimitate the 'intention' test and that wrought goes away.

Also, many assets go up in value over time above the rate of inflation because some poor bugger has invested their time and energy into building them up - something you are unlikely to get a tax credit for.

You are suggested income from labour which was not paid as wages or salary, so no PAYE/tax. increase in wealth from labour should be subject to tax. Currently you can hid as a 'captial gain' and get away with it (hence why builder/ developers/ traders are tainted in respect to land transactions).
