In a nutshell, because it’s a non-issue:

A quick article on it but all verifiable facts. Basically inbreeding creates a very small increased chance of genetic defects – and many of those don’t manifest till well after sexual maturity anyways (MS for example).

Unless you’re basically *trying* to aggressively inbreed – Ie. dad has kid with daughter, then daughters’ daughter, etc – it’s not a massive threat. Just marginally sub-ideal.
