You are grasping at straws and ignoring these major points.
1. ROC represented ALL CHINA and replaced by PRC. Nothing changed.
2. The current constitution of both ROC and PRC is that Taiwan is part of China.
3. Taiping Dao was occupied by KMT Taiwan right after WW2. A good 20 years before the 200nmi EEZ and over 20 years before any other country lay any claims.
4. Taiping Dao is an island by UN definition thus entitled to 200nmi EEZ.
You may grasp at many straws in your argument but do not ignore these major points.
As in your argument on Wen Ho Lee. You grasped at the straw of Wen Ho Lee admitting to one minor charge and ignore the fact that over 60 FBI agents could not find him guilty of the other 58 more serious charges.
Do you even know what does it mean by clutching the last straw? Seems to me you are the one that clutching the last straw. Because what you do is just keep repeating what you said, without any evidence or fact as back up.
1.) So you are saying before 1971, there are no such sovereignty entity exist as to what we know as China, People Republic of? Also, if and when a country got replaced by another entity, things DO changes. If nothing has changes, then Slovakia would not be a country after it was separated from Czech Republic in 1993? Hell, it along with all the former Soviet States should belong to Russia when Soviet Union was changed to Russia. If there are nothing changed.
2.) Not according to ROC constitution, they still claim Mainland China as part of ROC, you confused between country and governments. Do you even know the definition of being disputed? The reason why PRC government have no control over ROC is because the control of Taiwan was disputed, and just because you or PRC government say it belong to China doesn't necessarily mean so, if so, there will not be a dispute in the first place.
3.) Set aside whether or not ROC is a apart of PRC. The UNCLOS report said there were settlement a lot longer prior to WW2. It's goes into 1800s. Just because ROC settle in Taiping Island 20 years after WW2 does not mean there aren't anyone settle in it before.
4.) First of all, I never heard of the UN having a definition of "An Island" UNCLOS have the glossary as to what is an island. But the definition of an island have no bearing to any of the law of settlement. The UNCLOS definition of an island is simply "a naturally formed area of land, surrounded by water, which is above water at high tide"
Second of all, you also need to demonstrate China have claim Taiping as Terra Nullius, which is something China not able to, that is why the Chinese lost the UNCLOS court case and lost the subsequent PCA appeal. Just because you claim it is, doesn't mean it is, show me proof why's that is the case and I will believe you, but seeing a team of Lawyer form China cannot argue the case, I don't think you could. Do you even know law?
And about Lee Wen Ho, I am sorry, but did he plea guilty and went to jail? HE DID. And I don't really care if he did or did not do it, he plea guilty,
BY LAW, HE IS GUILTY, that is the definition of pleading guilty on something. Whether why he plea guilty is another issue you can explore, but unless you are him, or his defence team, you will never know.
Also, just in case you are wondering, in US, there are something called Alford Plea, which is a admit to a crime but do not admit guilt in the process, that is also the same as pleading guilty to an offence, but you do not admit guilt, you just admit you will most likely lose the case had it went to court. Lee's plea was
NOT an Alford Plea, that mean he know what he is getting, but you seems to think you know better than him, or his legal team.

Now that's clutching the last straw. But hey, what do I expect? You to know law? LOL
