I don't know where you've got these ideas from, but there are plenty of mistakes there.
Now bitcoin was produced by an individual (s) who is from a particular country so other countries wealthy men instructed their government
I guess that you meant there bitcoin was invented or created...
Even more, since the identity of Bitcoin's creator is unknown, hence his country of origin too, your statement cannot hold.
There will be no central bank and other financial institutions.
There will always be financial institutions. But some may/will/should choose to work with bitcoin (too).
Bitcoin is the Best Option to remove inflation.
Bitcoin prices fluctuations make it difficult for many to keep all their funds in bitcoin. Even more, if they earn fiat they already lose by inflation (if the cost of working hour is done in fiat, it's subject to inflation).
Companies are using inflation to suffer the poor masses/Citizens.
It's the state who plays the inflation game. Companies may rise prices more than they should and blame inflation, but that happens only where there's no proper competition (usually weak state, weak law enforcement agencies).
