First point is valid, allowing people to inflate asset purchase prices would benefit family owned businesses, farms long term holding, but would not benefit trading gains.
Second point is stupid, income is taxed when it is realized(mostly), should my babysitter pay taxes on the money I pay them from my already taxed income, of course they should. Corporate income should not be treated differently. Corps can already transfer money to other corps tax free in the form of dividends.
Last point is also stupid, all taxes are a tax on future consumption. Corps are allowed to deduct their expenses from their earnings before determining taxes. Most people can deduct only a fraction of their living expenses from their income.
Corporations already have many tax advantages. I know, I have one and pay half the taxes I would pay if I paid myself a salary.
