I know, most developers don't like their software forked, but I have real technical reasons in this case.

The real satoshi is talking about the possibility of future chain forks here (i.e. BCH and BSV etc.,)
No, the real satoshi is clearly NOT talking about the possibility of future chain forks in your quoted passage. The real satoshi is manifestly speaking to the topic of alternate client software implementations working on the same blockchain.
What was it he said in the same discussion immediately preceding? Oh yes:
[emphasis added]
Any such requirement is in your mind only.
'Should be able to'? As in, from a philosophical viewpoint? No, I don't. Then again, I am of the opinion that taxation is theft, but I pay what the people with guns insist I must anyhow.
Or maybe you meant as a practical matter? Is an 'are jurisdictions _able_ to force changes to the blockchain'?. I don't think so, but I am not 100% positive.
Bitcoin has so far exhibited a fair amount of resiliency. However, governments have created coordinated responses to other limits to their power. And all that hashrate comes with a physical manifestation with defined geographic locations. Which are therefore subject to the dictates of Men With Guns. If such Men With Guns mount a coordinated campaign against >50% of the network -- however improbable such coordination seem -- then yes. I can certainly envision the possibility that governments can force changes made to the blockchain. Any blockchain.
But this state is completely independent of any mutterings Craig may make. And are true for any and all PoW blockchains. BTC included.
So while you seek to vilify BSV for one person's mutterings on the topic, the utterances are completely unaffected by -- and completely without effect to -- any reality regarding the topic.
