In
theory it is possible to build larger bombs. In practice, it is likely that practical problems would crop up.

delivery is not problem either, submarine or torpedo, or just simple ship an do tha esily. of course that will be suicidal mission. gigaton range weapon probaly do not require delivery at all. in any case all humanity will die, no matter where is location of explosion.

Why would all humanity die? The energy of the 2004 tsunami was about .8 gigaton. Assuming the energy of a nuke could be coupled as efficiently to the ocean (which isn't a given) I would expect similar results. Not nice, certainly, but not the end of humanity.
As a rule, bigger bombs are less useful. In the early days, rockets had decent payload capacity but horrible accuracy, so larger bombs were used to compensate. But the destruction radius from a 10 megaton bomb is not nearly 10 times that of a 1 megaton bomb and the same holds true with a 100 megaton bomb.

these kind of wepons are not for attack but for defense from inteligent life forms. unfortunately and fortunately terorists dont count being inteligent, so they cant make such things, and nobody is going to make them for sale.
Original usage was simple, if we die we will destroy all earth. but as I see that is fine for suicide bombers.

Whoa! Now you've gone from theoretical bomb designs to terrorist nukes. Building a first generation fission bomb is tricky enough. Building a sophisticated multistage thermonuclear device is much, much harder.

Anyway with today technology and knowledge is quite trivial to make nuclear weapons, plutonium enrichment can be made even at home, however th bigest problem ir to stay alive while you do that, and pay the bills for electricity. also raw materials are not possible to get easily. but if you own nuclear reactor that is no problem.

Uh, no.
Uranium enrichment requires very large scale industrialization. This may be possible for a government, that's about it.
For plutonium, you have to build a reactor, you have to process the fuel properly, and it still takes time. The industrial scale is somewhat less than uranium enrichment, but by no means small.
Then you have to build the bomb. A first generation plutonium implosion device is more difficult to build properly than a U235 gun design. A first generation design also is unlikely to be frugal with material.
This is all far from easy.
