Inflations impact on BTC?

Genuine question from a guy that isn’t very fluent in finance:

I constantly see posts on this sub, and other crypto subs about price predictions. “XXX will be $XXX,XXX by the year 20XX!” But does anyone take inflation into account? The general consensus seems to be that bitcoin will surpass $300k by 2030, but how do we know that $300,000 won’t be pocket change by then? Will your $X investment even out with inflation? Will the actual profit even be meaningful? For whole-coiners, is this a viable retirement plan? Or is this something that will put a very small dent in an affordable mortgage or pay for an economy sedan in full?

I think with everything we’ve seen in the last few years with inflation seemingly skyrocketing and homes becoming so unaffordable that people are dreaming of buying the crappiest shack of a home in the worst neighborhoods, is it worth diversifying our investments and hoping one of them stick? Or is bitcoin truly the way to financial independence?
