Money spent on Chinese goods inevitably leaves the country draining our economy while bolstering theirs.
When you buy American made goods you exchange money (purchasing power) for a physical product (wealth). It's an even exchange. The purchaser gets a product which has value as an asset. The creators of the product get their money back (plus a little more) that they can then reinvest or use to purchase other goods and services in this country, repeat, repeat, repeat... This creates economic growth and adds wealth in the form of capital to our country and We The People.
Here's a micro example. I'm one of the owners of a General Store in my area. Let's say I buy and stock my shelves with nothing but Chinese goods. Most of that money I spent goes to China where a large portion of it will be reinvested in China. On the other hand, if I buy from only local producers that money goes back to those who might buy my products or services.
It only seems like common sense to me that you should buy from those that you would like to (or are most likely to) sell to. Rational self-interest is the driving force behind capitalism.
I do concede that I didn't really meet this parameter of your challenge, "that wouldn't also suggest we shouldn't consume oranges from Florida..." However, when applied to my argument I believe it becomes fallacious (reductio ad absurdum.) I'm not saying that I only want to trade with my wife or neighbors. There is also always the issue of scarcity.
Let's keep the rational in rational self-interest.
