I'd rather go the other way, get the government out of picking winners/losers here and institute across the board apt tax while wiping out income/capital gains/inheritance taxes (keeping ss and gas taxes because they correspond with payout).
Depending on what your goals for a taxation system are, that's downright terrible. I agree with wiping out income tax, but not all capital gains tax. (I would eliminate capital gains tax on investments that produce new wealth - like profit made off buying new machines to build new products, but keep the tax for all "buy low sell high" gains) Inheritance tax I'd change along with property tax in general, which I'd change to be percentile based; that is, your tax rate is higher if you are in a higher percentile bracket of total wealth.
Consumption taxes are bad, because you are taxed if you have to consume (or the system must have complicated exemptions for "minimum allowed consumption"), but if you have extra to spend, you will (on average) consume less (in nominal terms) if consumption is taxed and you have the option of not consuming. Unless the taxing entity (government) adequately creates evenly-distributed demand with its tax revenue, consumption taxes will be a drag on the economy.
