To start with, the era of Meme coins seems to depend on hype, that is, if the hype is not strong enough to push them, they will struggle, a good example is what is happening now, Doge seems to be on the low with nothing much happening and all the news about Doge foundation and so on, seems not to have any effect. Shiba Inu on the other hand, also depends on Doge, if Doge moves, Shiba moves as well, and with such case scenario, Shiba will find it hard moving or pumping massively to a reasonable price.
Lastly, with regards to the total supply of Shiba Inu, it will be difficult to attain such price, unless a massive bull run takes place again in the nearest future. But I would say, do not depend much or put much interest on such price, rather allow the crypto space to play it out, you can buy and keep for long term.
