I think the technology is great. The technology itself gives absolutely no reason for those who don't own bitcoins (in the main block chain) to buy them for any value.
Want to transfer value to someone half-way around the globe without dealing with Western Union, paying huge international fees, or giving your personal information out? I invested in a Chinese company which went on to pay my investment back and I still collect weekly BTC dividends. I never had to pay more than a dollar in fees the entire time, or give anybody my information (except the tax man).
Circumventing government controls is part of the value, the other part is removing the balkinization of finance which has made a global economy impossible or extremely unaffordable. Imagine being able to 'settle' a gold transaction with someone within 10 minutes, knowing it's not fake gold, half-way around the world, and being able to spend it immediately after back in the 1800's. What is this USD you speak of?
Secondly it also excels in that I can send money to someone I don't know for a service, and while they could disappear and run without me having much recourse, they can't steal/lose my bank details or credit card number. There's a different level of risk, one that pays off with small transactions rather than large. Credit cards are the other way, I'm unlikely to call mastercard to reverse a $0.2 transaction, and lots of the consumer protections (in the UK) only apply on certain size transactions.
To pay for something, I have to give someone enough information to take money out of my account. To send bitcoins to someone, it's up to me to send it.
The other reason is that they feel that, without transaction rate limits, mining won't be profitable when the rate of coin subsidy drops off. Some argue that we need the competition for limited block space in order to drive fees up enough to keep mining profitable. Those same fees kill microtransactions.
Since a hard fork would require agreement from essentially everyone involved in Bitcoin, there's essentially no chance of this limit being increased.
The bitcoin network underwent a hard fork a couple weeks ago due to a bug in the implementation of the on-disk database.
The developers reached out to the mining pools and got the vast majority downgraded within 8 or 12 hours. A day or two later a new version was pushed out that mimicked the old behavior up until the point that a supermajority of nodes were upgraded, and then switched to the new behavior.
Forks have happened before, and the community is close-knit enough to resolve them. Everyone's primary goals are a) being ideologically neutral and b) keeping the network running, in equal measure.
That's simply not a lot of data anymore.
