@Sigma33 so there is a review concerning in some way Harry's entitlement into security protection in the UK?
I agree with you completely that there is no assumption that the system or the particular decision is wrong but that it is right that any possible unfairness in the system is reviewed.
I'm parroting you there not to mock but because I suspect (though am not certain) that is what the High Court decided and you are describing it. I note also that Harry was advised that the outcome might not be the one he desires. I'm paraphrasing there but that is the general gist.
Harry might have made an unwise decision and might spend a lot of money. But it is his decision and his money. It doesn't make any odds to me. I don't know why it makes any odds to anyone else. I suppose someone might say he is taking up court time that could be devoted to some other issue. But since the High Court has allowed the question to be asked they must have considered this a matter which needs resolution and that this is the best way to achieve that.
If the High Court has decided there is some merit in proceedings then it's not for us to argue but to sit back and watch.
If he loses, and he might well do, then the issue will be solved and unless he can appeal to a higher court (and he might not be able to) then he will have egg on his face which should make people who don't like him and Meghan happy.
If he succeeds, however unlikely that outcome, then the unfairness in the system can be altered.
