Review Detail of lookbehindyou in The Mech Touch

Minor spoilers. I love this book, I'm at chapter 1500ish but the ark when he's at war is kinda bad. I skipped 600ish chapters and still know every charater that is still in the main story. Idk but the rest of the book is really good, and there's a mini cat ves ark. Worst part in my opinion as a recurring theme, not that just that one really long filler ark is that his system is kinda wonky. Like if your earn x money from mech selling you get 1 dp, but you also get dp from virtual mechs. So why don't he just make a bunch of passable cheap easy to use mechs in iron Spirit? Even tho their is a limit, virtual mechs are easy and cheap to make. What stops him from making an alt that auto buys his own stuff? Why was there an ice cream cone that cost 7 billion credits that the book said alot of people were buying, when an entire warship costs 2 billion? Why do pirates care about the big 2's laws? If you can nuke an entire planet in 1 shot I don't think a mech boi can stop you. What stops monoploys from forming on smaller planets? Where are the aliens that humans are at war with? shouldn't there just be one universal brand for mechs? Like if a master mech designer makes a cheap mech using their super skills and wealth that is factually the best bang for your buck shouldn't that be the best choice for all normal pilots that aren't experts or rich? Wouldn't that make it impossible for other starter mech designers fail, no matter how genuis they are? My personal answer? idk.
