And Goku and the gang non busting planets make sense. They're heroes, they have no reason to. The villains on the other hand...why wouldn't they? Especially those who can survive in space? PIS? CIS? Even if that's the case, it's faulty to say or assume that DBZ characters can tank planet destroying blasts, because if they did...well, the planet would be gone. It doesn't make any sense. Planet busting attacks, 9/10 are hyped up and charged for a few moments. And most of the time in DBZ, most attacks aren't anywhere close to the planet busting scale. Even the ones deflected or dodged resemble nukes at best.
I agree that, generally, a higher power level means higher stats, but to what degree? It can't really be proven one way or another if someone from the Frieza saga shattered a mountain with a blow and in the Buu saga, did the same thing with the exact result. There's no system to break it down with.
If we put all our stock in the power level theory, it just snowballs into absurd claims that nobody can really prove one way or the other.
Why cant we prove anything like strength output? Like I said before, Nappa has showings that put him at high end 100 tons along with speed combat showings of dodging bullets coming from numerous of fighter jets, ships, tanks, etc... without being touched. Nappa has taken down armies better than any high herald that I have seen pitted against armies by using his speed, strength, durability and energy output. We have seen Thor against fighter Jets, we have seen Supes against tanks (during the imperex saga) and it wasnt impressive at the least.
I dont understand the things that you are saying about power levels because it is pretty clear to me. A human has the power level of 5, master roshi had the power level of 100 and humans was unable to detect or see him fighting wise. He is far stronger than a human etc... Goku and Picollo during the raditz saga both was at 500 and Raditz was 1200 and they were physically slower, weaker, and less powerful than raditz by a large gap. They couldnt even touch him until they had to play trickery on him.
Frieza had plenty of reasons not to blow up namek. Frieza had plenty of reasons not to just go around destroying Galaxies. Frieza wanted to rule and he wanted to do it with an iron fist. That was the main reason he wanted immortality. Same for Vegeta; Vegeta had no reason to blow up earth since, well, he came there for the dragonballs. The androids didnt have a reason to blow up earth, their main reason was to hunt Goku down and kill him. Cell boasted about his power and only wanted a challenge, he didnt want to destroy everything... that wasnt his purpose.
Fat buu, thats all he wanted to do was eat. Super buu, same as Cell, he wanted a challenge. Hell, he flew to the lookout just to find Goku and fight him. Merged buu tried on numerous of occasions to destroy everything but he was stopped by Vegito. Kid buu blew up every planet looking for Goku and Vegeta. He thrived to fight them.
No villian on DBZ ever wanted to just destroy EVERYTHING. That would have been just ridiculous. We all know that Celestials can destroy everything, why havent they done it yet. There are evil one out there so again, why not just blow up everything when you can? When Thanos had the gauntlet, why didnt he just destroy everything? He had the power, why didnt he do it. Its all based around PLOT. It was stated how powerful Cell was, it was stated how powerful frieza was. People were there to stop them from using this said power and you want to know why, PLOT.
Speed? From what I have seen, I cant spot a high herald that has done anything CLOSE to what DBZ character has done. Again, all the things that has hit high heralds, all the attacks that dropped them wouldnt happen to a DBZ character because it wouldnt touch them. I can give THOUSANDS of scenerios but thats all you would do is throw them off as low showings.
