AvE makes a lot of generalizations. What he says about technical topics is generally right enough for anyone who doesn't make a living designing the things he discusses. Those people would do well to understand the underlying theory. >If you don't replace the oil regularly, or let it get so hot it flows out of the journal, the bearing will wear and need replacing. It's still going to wear out from cold starts and the entire rest of the engine that doesn't have pressurized lubrication is also going to wear out eventually so there's no point in trying to outlast all those components since you're gonna have to take it apart to deal with them when they reach EOL and you can just deal with bearings at the same time.
