It kind of can, but trading futures is trading termed contracts, kind of like options, but a bit stranger (and you can buy options for futures contracts too!) For a retail trader, you definitely are not in a buy and hold/invest mindset. Often people use futures as a hedge or for locking in prices for physical delivery- it serves a very real world problem.

If you consider 'trading' to be short term buying and selling of stocks, then yeah. Holding stocks long term is nothing like trading commodities though.

I suppose if you're shorting or trading options generally, yes to some extent.
