It's balance dude, things are rarely black and white. Broberg isn't who i would have taken but he's a first round talent and no one ever knows how that will go, especially dmen. Balance isn't spinning his lack of production in the SHL at 18, which is not a red flag at all historically, into proclamations of a bust. It's not acting like Nurse isn't a quality level of player to get at 8 overall when the dude is a quality top 4 dman playing shutdown minutes on a good team. He's +10 since his rookie season, how many Oilers can say that, and he's broken 40 points while being still just 24. Nurse is a very good player even if he isn't elite.
It was a scary pick, that doesn't mean we should be expecting or looking for a failure. I'd also like to hope Broberg is better with the puck than Nurse but the truth is Broberg's story hasn't been written and being compared to a guy that likely every team in the league would want shouldn't be seen as a sky is falling scenario. Nurse isn't a perfect player, his breakout leaves a lot to be desired, but man he's a very rare combination of size, speed, toughness with decent skills. It's a combination rarely found outside of the top 10 in any draft, especially when it's one of the youngest guys in the draft like Broberg (Lavoie for example is nearly 1 year older). I don't think Nurse is a #1 D but i recognize he has the skills to succeed in a critical role as our shutdown D and that role is hard to fill and rarely done so at 24. Broberg isn't the ideal pick in my mind either but it doesn't mean he's bad just like Benson isn't bad because we could have take DeBrincat. Heck i wanted Ristolainen over Nurse, pretty glad that didn't happen.
Remove the emotion and look at the evidence, the evidence suggests he's on pace to be a player but the degree of upside historically isn't obvious at this point. And lets be honest if Broberg is an excellent two way guy at evens does it hurt us that much if the offensive upside isn't there to QB a PP? Bouchard and maybe even Samorukov or Bear have the potential to fill that role and Klefbom is doing it right now on a #1 PP. This team needs difference makers at evens and if Broberg is like Nurse at evens offensively and defensively then we shouldn't have a lot of regrets. And since you apparently missed it i'll post the 18 year old SHL dman stats again:

This is the last thing i'll say on the sincerity or rationality of your views. Being balanced in assessing the future i would suggest involves being both skeptical and hopeful and then using the info available to determine where you lean. You seem to lean towards skepticism with little to no desire to look for hope, and from my perspective even discounting/ignoring relevant data that suggests otherwise, and that's not reasonable given what we currently know about the team and this player. I know the losing has been tough but i just honestly find it confounding how someone so jaded could continue to be so invested and still be a fan. You seem like a masochist or something. lol.
