What if people convince governments of their nations to make Bitcoin as a legal currency or what if we agree to give tax on our bitcoin income? Will government then make Bitcoin a legal currency.
We all know that bitcoin is a decentralised crypto currency and thus there is no such proper authentic regulating body over the bitcoin who could keep eye over all the bitcoin activities and thus there is improper high bitcoin transactions fee and moreover there is also increasing illegal use of bitcoin so in order to stop this illegal use, the global centralisation of bitcoin is very much necessary, no doubt governments will impose high taxes over the bitcoin for its transactions, for this negotiation with government can be done but its centralisation is very much necessary.
I was about to call the same problem and first searched the thread to see if anyone else has noted it, then I sow your post but I don't agree with all your points. Illegal use isn't something that's done only in blockchains, if nothing else it's easier to find out here because of the transparency... at least in theory.
First of all, yes BTC is decentralised which makes it almost impossible for one person or one team to come in any kind of negotiation with a government. However a government could potentially PROPOSE something, a rule or a change to the BTC network, then this could be voted by the community to decide if they accept it (and possibly result in a two hardforks
).
Ethereum has a body of representatives though, in their case someone like Patrick Storchenegger (more about him here:
https://www.ethereum.org/foundation) would be able to take a first step into making ETH more widely accepted.
Some benefits of promoting BTC to governments would be more news like this:

PS: I don't know if Florida is indeed accepting BTC for tax payment right now, not yet or if they may never accepted it after all.
