No this is:
The primary advantage of a 401k or IRA is that the (tax deferred) additional money you pay into your investment *grows* tax free. Do you understand the exponential function? If you expect to be fabulously wealthy, you can do a Roth 401k and pay no taxes on withdraw. If you're arguing against tax managed funds then 
while you might think that your money is at an advantage growing tax free you are going to get nailed on the distribution phase. One way or another, uncle sam is going to get his cut. People that are relying on their 401 k's for retirement are subject to the following risks:
1-CONSTANTLY changing tax brackets
2-market risk
3- fees
4-loss of liquidity( they cannot touch their money until 59 1/2)
5-funding the account in a Low tax bracket, then possibly collecting from a higher one.
