Price really matters for those investors who bought some bitcoin at a high price, and faced with a bubble. That people will be very disappointed that they will have sell at a low, or wait few years till price recover or increase.
Bitcoin is not a get rich quick scheme and those investors which doesn't understand this basic thing always loose money in bitcoin world due to panic selling as they think that the price is dipping and it's better to have less money than no money and they sell their bitcoins in a bearish market.
Panic selling is human nature, and we can't stop this. What you said is correct it's better to have less money than no money. All people mindset is like this. No one will ready to lose their money. If you have patience and market knowledge then you will not get panic you will wait for the right to sell your coins.
We cant erase that to the minds of some users here considering there is a history with bitcoin that went down so bad many times specially the part when it almost loses its value.
That is why its price always matter. When people see how great the amount of one thing is they tend to have faith in it. Add up the price to where it could reach.
Just like gold now which is at $1200+ but it can also reach at $1300+ so people are aiming for that number and put their faith that there will be a time it will reach that price again.
