I don't see where I said that? I'd be much more interested in an anonymous sidechain than crypto-ebay though to be honest...

The issue is the premise of your argument is that Open Bazaar hugely popular market place might get choked out of transaction room.

I advise your to get rid of these disease that is trying to satisfy inexisting demand because "I swear" mass adoption is coming. To quote:

I never made the claim that mainstream was coming by tomorrow. The thing is that you and I don't know exactly from where it will come and when. Will it come from a killer app? A monetary crisis? A mass marketeer campaign by the big boys? We don't know. What I do know though is that it will NEVER happen before we let enough room for it to happen.

Accusing Blockstream devs of conflicting interests is an ad hominem attack, especially given their years of contributions in scaling Bitcoin to 1MB.

My posts demonstrates a confluence of interests between Blockstream and Bitcoin, which dispels OP's fuzzy evidence-free accusations of impropriety.

Icebreaker,

"ad hominem" means relating to a specific person.  We were talking about whether
people who are core devs have an conflict of interest with a private VC backed
company.  THAT is the issue.  You were the one who started praising 'Backamoto'
and 'gmax' while bashing Gavin and Hearn.  so those comments were ad hominem
and have nothing to do with the issue.

For the record, I greatly respect Greg Maxwell, Adam, and all those guys.  However,
they are not great communicators and have not been very transparent about Blockstream.
Maybe they have expressed some opinions on some dev mailing list or IRC but certainly
nothing clear that I've seen.   As a general member of the Bitcoin community,
I haven't heard much from them.  Maybe they don't care.
On the other hand, I've seen very clear and cogent videos
and articles from both Gavin and Mike Hearn.  

Therefore it shouldn't be surprising that
 I'm utterly unconvinced about this 'confluence of interests' of which you speak,
given their lack of communication and apparent stonewalling of the blocksize increase
(which has been discussed to death).

If you are convinced, great.  More power to you.

Everything have been discussed in length about the escrow and reputation system to ensure an E-Bay like security. I invite you to read more about OB. Of course it won't be risk free, nor is E-Bay.

This is the most stupidest answer I could ever imagine about the block size. The block size in not exchangeable. The block size as no value per se.

Hey icebreaker, want to trade some block size? 

I do.  Fork the motherfucker and I'll split my coins and sell off the XTcoin's ASAP.  If I can find anyone dumb enough to take them and the market doesn't take to big a dump before I can get in the game.

XT has one chance:  The govt mandates its' use as part of a crypto-currency license.  In that case all of the corporate vendors and Coinbase's and such will have no real choice to comply or close shop.  This is not outside the realm of possibility actually.  To save us all from them evil terrorists and Chinese miners and so on.  Unfortunately a lot of people would swallow that one hook-line-and-sinker I'll bet.

Examples?

Rough recollection after reading reddit/fora (I could be wrong).
Mike: Adding levelDB, implementing bitcoinJ
Gavin: Relay network proposal?, counting codes on blocks to trigger fork in xt
For both: Code reviewing a lot of core code
