That's a bad example you're using, how would he seal a tbb when it's an incoming projectile?
He has SHOWN however that he can seal chakra into someone else.. he took his and his wife's chakra and sealed it into naruto.. so your argument that chakra can't be sealed is completely false
how would minato not being able to seal a TBB because it's a projectile be any different from not extrapolating totsuka's abilities to seal things that don't have souls? Both are giving them feats that the manga does not necessarily show they don't have, without a burden of proof to prove that they actually have that ability.
you seem to not get that the absence of evidence isn't the evidence of abscence.. those no limit statements aren't proven wrong, just as they haven't been proven correct.. you can't claim their incorrect nature as you don't have the evidence to support your claim.. just as I can't claim their correct nature due to the very same lack of evidence
In a manga where we have limited feats and showings, absence of evidence IS evidence of absence. Going by this same criteria you are using, I could easily extrapolate any characters abilities far beyond their canonical limits and give you the same 'absence of evidence isn't evidence of absense' argument. I could say BM Naruto can make 1,000 BM clones all who can spam super bijuudamas and use flash shunshin, and give you the same absence of evidence argument since he never attempted to do so. The same applies for many techniques and character abilities.
Fuuinjutsu is a broad category of techniques that seal different things, just having the label fuijutsu does not mean it gets the feats and abilities of all the fuinjutsus. It has not shown those abilities in the manga canon and by the databook entry on the other page, I did not see the quote you made about it being able to seal anything it pierces, I only saw the quote specifically talking about it sealing personal beings.
What I am saying, is that it isn't really a no limit statement because it can seal other things.. Fuinjutsu on the WHOLE as ive said already, have been seen capable of sealing inanimate objects, souls AND chakra alike... so you CANNOT dispute this fact..... and by that very nature, totsuka sword , which is imbued with sealing jutsu, would be able to do the same as already portrayed in the manga
