Why scaling bitcoin would make it be less censorship-free?
Well, does the solution allow full nodes to function over anonymizing networks like ToR, for example.
I think you are confusing BIP101 and XT here. This arguable DDOS protection implemented in XT has nothing to do with scaling issues...
Anyhow, bitcoin is much more than just censorship-free money.
Maybe we are getting to the crux of the divide. Bitcoin is different things for different people. So it's expected that they would argue for changes that enhance a particular property.
I look at it like this. What does Bitcoin allow me to do that nothing else on the planet allows me to do. Those properties are what I consider Bitcoin's real strengths.
Bitcoin is indeed a lot of thing for a lot of people and should stay as such because it is what makes its strength but I fail to see why scaling it would/should change any of this.
