Answer 1

We build them with a “permanent” alignment

Then you hit a pot hole and things bend slightly. Now the slightly bent system hits other bumps and bends a tiny bit more

We do alignments to cancel out all the random tiny bends that will occur because we don’t have infinitely rigid rods, they’re stored beside the infinite ideal heatsinks and we lost the key to the shed.

Leaving the ability to adjust increases the longevity of all parts involved otherwise instead of being able to make tiny adjustments to cancel out changes in suspension strength or exact angles of connections you’d have to replace everything to get it back to target and that’d be way more expensive. You’ll still need to replace things eventually but the ability to adjust for the real world reduces serious maintenance
