What he said is that others countries that doesn't have a solid electronic transaction system are actively trying new stuff. In that case, M-Pesa won that race but the fact that it was centralized isn't why it won, it won because it was needed.
Now does Bitcoin is needed for another country? No idea, but I would have said the same for M-Pesa.
For instance, "Bitcoin is a bubble" only makes sense if it's its own unit of currency. "M-Pesa is a bubble," "Square Cash is a bubble," etc. aren't meaningful statements to make; they just support transmission of the underlying currency. ("Kenyan shillings are a bubble" is a meaningful statement, but I've never heard anyone claim that you should use cryptocurrencies to insulate yourself from hyperdeflation of a fiat currency.)
"Bitcoin is environmentally dangerous" only matters if proof-of-work is relevant; in a centralized system, you don't have the problems that lead to you wanting to even consider proof-of-work.
"ICOs are a scam" doesn't make sense in a centralized system. "The transaction rate is too low" isn't a complaint anyone has about a centralized system (the usual complaint about the US markets is that the transaction rate is too high, and HFT should be throttled). And so on and so forth.
"environment": Proof of work systems ensure that the ledger is secure and worthy of trust. Proof of Authority systems require trust, where the ledger is secure "because we say so." Isn't this the major reason why people are fleeing from legal tender? People can't trust the issuers, the processors, or the banks because they're colluding with politicians who provide bailouts using taxpayer dollars?
"ICO scam": absolutely makes sense in a centralized system. Are you actually claiming that people don't create scam companies with centralized currencies? Because why? Even legitimate companies can be slandered for the same reasons that people call ICOs "scams". The Franklin Mint, for example, produces coins which are sold on late-night infomercials that have little-to-no intrinsic value, but people buy for speculative reasons. Are they a scam? The reasoning is identical.
"slow/expensive transactions": One of Bitcoins main value propositions is aiding in international transfers. The centralized systems were too slow and expensive, so a better alternative was developed. Saying that speed and expense aren't complaints that people have made about existing centralized systems is simply wrong.
And so on and so forth.
