Would Kid Goku Knowing UI Have Made A Difference Against The Various Foes Throughout The Series?

Say that Goku used the time machine to go back to the 1st chapter of DB and transferred his knowledge and mastery of UI to his 12 year old self just before Bulma arrived. Given that UI in the manga is far more about improved fighting skill rather than being more of a power up as the anime depicted it, would Kid Goku knowing UI have made a difference against the coming threats in the years leading up to DBS? As in, if Raditz(or any of the other threats from outer space) came to Earth earlier than expected, would Kid Goku be ready to take him on?

He would wreck everyone he ran into.

What scenarios would he find himself in where he doesn't overcome the odds? I mean the environmental traps such as Pilaf's retractable wall and the sleeping gas may still work but against actual physical threats these characters are going to be hardpressed. Tao Pai Pai and Piccolo Daimou should still push him to the brink of death by virtue of their strength being so much greater by comparison but they're going to exhausting themselves a lot more in the process. Fights against the likes of Tenshinhan and Piccolo Jr will prove to be a lot easier and I suspect Goku wouldn't have to wait until the 23rd tournament before winning.

Yamcha
Tao Pai Pai
Tambourine
Piccolo Daimaoh

Those were the only four characters that fair and square beat him up. Well, Yamcha did so because Goku was too hungry, not really fair and square, Tambourine also did it because Goku was depleted, but anyway, with UI, he beats Yamcha even being hungry, beats Tao Pai Pai, and Piccolo. Maybe he wouldn't be able to access UI if he is that out of juice against Tambourine. Maybe Tambourine still wins, but hardly goes home unharmed.

Although it's possible that with such an advantage, Goku would do what Roshi feared he would and get lazy due to overconfidence, since he couldn't find any challenging opponents, so he might stop training altogether.

If he had the speed and agility of UI none of his opponents would have been able to lay a finger on him

Post Master Roshi training, and Pre first world martial arts tournament, Kid Goku, with FULL Ultra Instinct in Base.. would STOMP Piccolo Junior for certain and I personally believe maybe even Raditz!

I don’t know about Nappa and Vegeta though.. These, I believe, are simply too strong for him. Remember that power levels are a thing still now that Goku has UI in Base, and can still increase his power by transforming to SSJ1, 2, 3, God, Blue, and Silver.

So my personal belief is:

At minimum: Piccolo Junior, from the 3rd WMAT

At maximum: Raditz

The more we learn about UI, the more I'm certain his child self couldn't handle it. So UI has multiple parts. There's the Technique part and the Transformation. It may also be a State. Kid Goku might have been able to handle the dodging technique but there's no way he'd have what it takes to even access the white haired form or stay in the UI state for very long.

He lacks many of the qualities Adult Goku developed to properly use this stuff. With the UI technique alone Goku would have an edge in all of the fights that were close in power, so all of Dragon Ball basically.

Overall, the power gap can't be too high or UI's effect is negligible.

Also, UI could be used against him, since even the State drastically tires Goku out. That's something to think about.

And let's use Saiyan saga Goku for a second. I think even with UI that he might lose to Vegeta. Depends on how big a power boost he gets from the State. For 1, it's unlikely he'll be able to use the Kaioken with UI, so he'll strictly have to use UI or switch between them which will tire him out quickly. And I think for him to even use the UI state at this level or lower would result in instant stamina drain or death such as with Roshi using the Mafuba in DB. I just don't think Goku would have the amount of ki necessary to sustain the state for very long if even current Goku barely has the stamina to do so.

I mean...he practically did that throughout most of DB.
