U.S. government bonds can be bought on TreasuryDirect without paying a markup. Nonetheless, Treasury bond funds offer instant diversification of maturities at modest cost. Remember that while conventional Treasury bonds are said to carry very little risk of default, they do carry other risks, such as interest-rate risk. And in these days of modest yield, you also run the risk that you may not be able to stay ahead of inflation.
