This is roughly how I was taught to estimate. It is accurate but takes time and everybody hates the result. Management halved my estimates without telling me, made fun of my mentor’s estimates, complained about needing to know everything upfront (not very agile eh!), etc. I think you are right and estimating is more of a solved problem than we think, some people just don’t want to admit it!
