That's my favorite part of Bitcoin, the fact that it can evolve over time. If it's found that deflationary really won't work, and it's genuinely hurting the usage and adoption of the currency, and it's in the current users of bitcoin's best interest to do so, it can be turned into an inflationary asset. Flaws can and are fixed in it, and because those changes can't be pushed through by some appointed authority without overwhelming majority from all involved parties, you don't need to worry about this ability to drastically change being unfairly pushed upon you.
