If the price of BSV rises significantly—say, X100 —the cost of inscriptions could increase if miners keep the minimum rate at 100 sats per KB.
However, economic logic suggests that this rate should decrease as mining becomes more profitable; furthermore, due to Moore's Law (and its equivalent in storage), computing technology is inherently deflationary regarding storage space and bandwidth, which would cause the minimum rate per KB to drop over time with mass adoption.
In conclusion, the cost of inscriptions might rise temporarily while these variables adjust.
