You say you can trade around the clock by trading around the globe. But a position in New York can't exactly be liquidated in Tokyo. You can hedge for an approximation, but then you have cost of carry. Most markets are also completely closed on Sunday. It's not obvious to your parent why this should be. And don't even mention the half-day for stocks in the US around Thanksgiving, which is just silly.

Important things are 24 hours a day. Spot and forward FX, commodities, sovereign bond futures, Equity index futures, etc. See for example:

CME tends to be closed for an hour a day for cleanup and that's it. US equities aren't a big deal compared to the size of bond or FX markets.
