I like that it is mildly inflationary over the long term, as opposed to deflationary.
Other the hand, Bitcoin doesn't have to replace the complete currency system to become a useful medium for transactions.
So, a low-level of inflation can still be maintained via fiat currency.
(We obviously need a certain amount of inflation to encourage people to invest vs. hoarding their money.)
Unlike managed currencies that target a constant rate of inflation (2%-3% in the case of USD), Ethereum creates currency at a constant rate forever. But as the size of the monetary base grows relative to the constant rate of issuance, the inflation rate tends to 0%.
Eventually, when the monetary base hits a certain size, the rate of ethers lost to bitrot, hardware failures, carelessness, deaths, etc. comes to equal the rate of issuance, the monetary base stops increasing, and inflation rate hits 0%.
Both a simple (and in hindsight probably obvious) solution to the problem of lost currency over time, and a nice compromise between inflationary and deflationary currency models.
