in 2028, bitcoin's price will be so large, most normal people cannot contemplate it.

If indeed BTC goes to a e.g. 1Mio$, don´t forget what it means. That the dollar as we know it, did crash. So do you really think, in such a scenario everything is like today and people can spend their time buying useless stuff like Lambos? That Lambos even exist still? The more the system crash the more unsettling things get. I don´t know what to expect but security infrastructure seems the key to protect bitcoiners from the army of nocoiners.
