This is not what I would agree with.
If I have 1 BTC then why do I need a bigger block size?
In time if my 1 BTC is going to buy me a house then the tx for buying that house will actually be tiny (it certainly won't require a bigger block size).
but think outside of the box..
now imagine its 2016 and 3 million people who grew with bitcoin and loved it for fast transactions in 2009-2014... (not hard to imagine, as thats the reality)
but these 3million people are now noticing bottlenecks .. soo this 3 million people will get pissed off with delayed transactions and so they lose faith in it.. and cause a price crash..
they will tell their friends to ignore the "we use bitcoin" video as transactions are not instant. are not virtually free and all the other issues that are very relevant and apparent right now.. and so bitcoin adoption falls.. not rises, because the utopian dream of bitcoin has been lost, and replaced by greed of miners and politics of dev groups
and now your dream of buying a house for 1btc is laughed at because the world can see that bitcoin dev's refuse to adapt to demand, refuse to buffer a safety net, refuse to adapt before demand.. and your 1btc never reaches the price of a house..
