There are many problems with your hypothesis.
1) For short or mid term investment, just about every coin is inflating at a rapid pace currently. It's the equivalent of living in Zimbabwe, and that's the nature of non-linear block reward. Doge will actually be inflating less than many other coins for short term interval, and negligible difference for mid term. The dogeflation will be 3% inflation in 2029.
2) Coins lost per year in crypto is a pretty high number. I think even NXT, which has a user base of what? 50 people? that bought an IPO managed to lose 5% already, when the thing hasn't even been out a few months. If you gave a conservative number of 1% lost per year, then dogeflation is only at 2% in 2029, and 1% in 2045. Things like car accidents, deaths, or natural disasters will also cause many coins to disappear from the economy. This is a variable most people just don't comprehend, and it might even be larger than most people think. Think about it, when a person dies and has a wallet laying on the bed, someone will eventually pick it up. If someone dies with an encrypted wallet, that thing is going nowhere. It's hard to believe, but it's possible the dogeflation might not even cover lost coins.
3) Broken PoW system - If your market cap isn't high enough, you can't keep a block chain up with transaction fees only. Doge has now placed itself in a position where it's going to exist forever even if it slips to #20 market cap, while other coins that some might consider "better", are going to fail without enough mining incentive. I was pushing for an infinite, non-zero block reward (1%) on Vertcoin for this reason, which would probably be completely canceled out by coins lost anyway, resulting in the coin having more security through higher mining incentive, while still remaining hyper deflationary.
4) In general terms, a hyper deflationary currency does not create a lot of economic activity because you can just horde money to make money, rather than invest it into a business or other venture. The Doge liquidity will now be through the roof since it has a small demurrage fee. Increased liquidity may lead to increased adoption, which then completely negates the demurrage, increasing it's value over competitors. It's the equivalent of AOL sending out millions of dollars in AOL CDs to everyone on the planet. Yes, it cost them money to do so (same thing as demurrage), but they probably made money from the investment. Doge is now the AOL of crypto.
I really could go on for days here. As for 0% vs 1% inflation, the %1 choice has literally no downfall whatsoever, since like I said, the currency would still remain deflationary due to lost coins, and it would only increase block chain security through mining incentive, but the seemingly much larger Doge number may cause it to outperform my safe, 1% choice through some of the not so obvious means I listed.
Another guy wrote an article covering some similar, and some different points to mine here:

Why are you quoting 2029, which is 15 years from now? So much will have changed by then that reliance on that year's numbers is highly questionable
