Yes I think it's enough
Because each Bitcoin can be divided into 100,000,000 units Satoshis sats. 1BTC= 100,000,000 sats, so this means that there are effectively 2.1 quadrillion Satoshis in total
So even if Bitcoin gets to a very skyhigh price, there will be no need to hold a whole Bitcoin to your self. We can just make transactions and save in tiny fractions. so that's it, if Bitcoin had an unlimited supply like regular Money, it would lose purchasing power and value over time
Do every holder of bitcoin presently own a whole bitcoin? No. Yet we all are bitcoin hodlers not because we all hold a whole but that we are holding some fractions through accumulations. So a sky-high price.wouldnt make a difference in the way we own or transact.
If value of cryptocurrencies were determined by their unlimited supply we would have gotten a lot altcoins having price value far above bitcoin because there are altcoins with lesser supply than bitcoin. Isn't it so?
