Ah, but what if you were also a biochemist, and so you wanted to vertically integrate your amateur gene lab by making your own reagents? Because I'm guessing that those $600 kits don't really have a $600 BOM...

No, but creating these reagents is a lot of work.

Principally create new flowcells coated with an oligo lawn would be difficult. Not impossible… but a non-trivial project…
