The great thing about it all is that there is most certainly room in this market for both inflationary and deflationary cryptocurrencies. I think as time goes on we will see the inflationary currencies like MIM and DOGE used as "currency" and deflationary coins like BTC/LTC used as more of an investment commodity (i.e., a store of value like gold/silver).
I think you are completely right. Which is why MIM was intentionally designed like this. Doge however was an accident.
