40 million USD (yearly DOGE inflation) is less than today's daily volume. Meanwhile this year's growth in the market cap is 3600%, meaning that the increase in adoption of the currency and resulting demand from that is thousands of times greater than the daily supply increase was able to meet. How is having 5% emission in any way a negative compared to 0% during this time? Are people seriously arguing for wanting to make just a tiny bit more than the X36 increase in one year? I don't think so - it is just an imbecilic argument that anti-Doges use to attempt to destroy the coin. Now if we are talking about the years to come, the growth in new users may drop off after a while, but it's probably going to take at least a few years until it drops off to below the level of inflation, and even in that case, there is still a decrease in supply from lost coins (likely more than 2% a year) and a decrease in prices from economic growth (2%), while by that time the percent of emission would only be around 3%! The best coins have around 1-3% yearly inflation, and yet only in the Doge section there is a constant shrieking about "muh inflation".

As for the initial release of many coins quickly (100 billion in the first year), I totally agree with you, it was done way too fast and seemingly recklessly, with the only goal of pumping and dumping it all onto a passive market. But it's been 4 years since then and a lot of the DOGE has been bought up, so I don't see any issues with it in the context of today's Dogecoin. It's really quite ironic that when they were generating the "endless infinite supply Dogecoin", which is a metaphor for the initial low hash rate 1 million, 500K, etc, Doge blocks, there was nothing said about it except hype, and after everything was sold, all sorts of trolls come out of the woodwork to talk about the "Doge inflation problem". Anyway, it seems that most of these initial coins were circulated through the market, passing through many hands, and so it's not an issue any longer. Also, it is much better for a coin to be mined like this (with an excessive supply at the beginning) than to be created within a centralized system by the decision of some person or committee (e.g., Ripple), which is not open to the whole market. A lot of these "developed coins with ... strong marketing teams" that you are referring to are probably just Ethereum tokens that can be created at will in any amount without being openly/fairly mined by anyone in the world, and it can be argued that they are not even real cryptocurrencies. Doge on the other hand has stayed true to the spirit of Satoshi's Bitcoin and so it remains as an excellent choice for any crypto investor.
