You overstated Europe's importance. Europe is very important but far from being the only purpose of BRI, not even a crucial purpose. Arab countries, Iran and central Asian countries combined is a huge potential that can match Europe. Many these countries can't even be reached by sea port without extensive road links.Trade over land is much less cost effective especially for China, since its most promising resource partners outside of Russia, are Africa and South America, both of which are far away. The Belt and Road land routes are ironically most useful for accessing Europe, which have fallen further and further into the US camp - a consideration Chinese leadership never seriously believed until recently, I think.
[addition]
Even for goods going to Europe, sea lane is only cheaper if the product is produce in coatal region close to a sea port. A product produce in western China will need travel eastwards for more than 2000km to reach a port, then travel 5000km through sea to return to alsmost the same point then another 7000km to reach European port. While going over land takes just 5000km and takes much less time that will beat whatever advantage sea travel has.
And I am not even talking about how rediculous for goods to go half of the globe from Xinjiang to Arab countries by sea.
Once again, BRI is not to serve Europeans or Americans (US) but to serve the world especially China's inland development. It is an evolution of "Western development" program (西部大开发), a decades long program.
