It's just basic tribalism. They first pick a doctrine/ideology and try to make the facts fit the theory. Bitcoin Maximalist are the banker equivalent of crypto-sphere. What reasons do bankers bring up against cryptocurrency - you can find an equivalent among Bitcoin Maximalists against any crypto that is not named Bitcoin.

There is absolutely zero technical achievements/moat that is exclusive to Bitcoin and most coins including Ethereum can do anything Bitcoin does better with more features.

To me Bitcoin Maximalists and Bankers are basically Republicans and Democrats. They are against each other. But a person with good sensibilities should avoid both of them.

Bitcoin Maximalists stick their heads in the sand when it comes to InstantSend that give roughly 1.3 second confirmations. hey refuse to accept on-chain governance. Any project that is linked to Bitcoin with the exception of Komodo is a failure while many projects on http://www.blocktivity.info are rocking it. The maximalists are also oblivious to the decentralization created by DPoS as opposed to few mining pools. PoW is nowhere as decentralized as DPoS: https://steemit.com/statistics/@vimukthi/forget-51-attacks-coingeek-now-control-67-hash-power-and-they-are-loosing-usd370-000-usd-per-day

Three Things Makes A Bitcoin Maximalist

• Arrogance/Elitism
• Being oblivious to facts and tech development
• Tribalism

Don't bother with reasons. They will use any logic/excuse/theory to fit their delusional agenda.
