Yes, if you used a no fee broker to buy and sell (everyday...) the constituent 500-5000 stocks typically in a large index fund you could avoid the very low management fee.
In practice, that’s ridiculous. The management fee on a good ETF is less than pennies on the dollar. It’s the full time jobs of many people to do this. It takes a lot of time. If you tried to replicate it yourself on an individual basis there would be significant opportunity costs as well as far increased tracking error, as well as other things I’m probably not thinking about off the top of my head. There is a reason no one does that.
