We certainly could - it's absolutely possible. The question is if it's economical and so far the market has ruled in most cases that it isn't. Either the project doesn't need such a perfect amalgamation of materials (maybe there is an expected deprecation that doesn't justify such an outlay - possibly earthquake risk would minimize any expected lifespan gain - possibly the materials contractor just can't internally justify the added material cost while remaining attractive to local contractors).

It's all a balance. Imagine a scenario where you can ship in specialized materials to build a bridge with an expected lifespan of 100 years and it'll cost 50M - or you could use local concrete that has an expected lifespan of 15 years and materials would cost 5M. This is a vast simplification of the math but, assuming those expected costs it'd be cheaper to build using local materials and just schedule replacement every 15 years. And, of course, there'll be egg on your face if you build the 50M bridge and then suffer a massive tsunami in two years that destroys the foundations anyways.

To paraphrase a Grady quote: "Engineering isn't a study of building the best thing - it's optimizing the quality we can get for the cost outlay."
