Europe licenses trucks and trailers differently than in the U.S. An American one-ton pickup can tow at a combined weight of up to 26,000lbs in most states on a standard Class D license. The same license you need to operate a Honda Civic. This weight would require a commercial license in Europe, raising the bar for entry.
The lengths of trucks and trailers is also regulated more heavily due to smaller European streets. A vehicle rated to tow a 26,000lb load in Europe would need to be much shorter in length to abide by these regulations. This is why you only see “cab-over” style “lorries” in Europe.
What follows is my opinion on some additional factors:
It’s more affordable for Europeans to hire a professional driver for heavy loads owing to the short distances between destinations. It’s also less likely that your average European owns land or has a need to haul a heavy load to maintain said property.
The Boca Chica test site in Texas is built immediately adjacent to a protected wildlife preserve. This is the site where SpaceX has been working on the Starship launch vehicle.
The second part about failing is extreme hyperbole. SpaceX is the most successful launch company in human history by any reasonable metric. I’d argue Musks distance from the company in recent years has helped.
