8. i too want less government, but any government above nation state will always suffer from a democratic deficit

Effectively the world goverment will be a nation goverment just one big nation....

and if the gov't doesn't respect the needs of the people it will lead to tryranny

I don't see why it would, not any more than currently elected goverments do, they would have to get elected just the same....

likewise if the people don't respect the mandate of the gov't then it will lead to insurrection.

It isn't something i would want forced on the world, its more a hope that in the future people will band together and all work for the common good. I realise that sounds quite communist but thats not the intent...

9. you seem very concerned about rich people dodging taxes, why is that?

Its not just that, but in general companies and rich people playing countrys off against each other to try and attract them.

you do realise that we exist in a generally progressive tax system, and that if you want people to pay tax due then the best way to achieve that is a simple tax system

Just make a far more basic progressive tax system... theres a whole industry around tax and its OTT in my opinion, have a progressive income tax on individuals and progressive profit tax on companies. Though all things considered it would be easy to cut taxes somewhat in those circumstances...

rather than complaining when rich people move to another jurisdiction along with their wealth generating innovation.

I wasn't complaining just listing what i see as the advantages...

and will the cannibals consent to be ruled by your world government?

It would be thier own choice... though i imagine some members of the government may take some issue with thier hobby..
