It would be like saying that we should just have used separate internets because the first one couldn't scale.
this sentence doesn't make any sense to me
Let me explain it this way. Bitcoin is nothing more than numbers in computers. From an economic perspective these numbers need to be scarce otherwise their value will ultimately goes to zero and be useless for trade and being used as
money. If your solution is to insert an infinite amount of altcoins in the economic network. The number used to represent good and services are not scarce anymore driving their value to zero and ultimately removing the economic incentive to use them.
i disagree here. Supply and demand make the price of a coin. Bitcoin isn't scarce enough right now because of this insanely long phase of high inflation (8% to 10% this year). This inflation bleeds out your marketcap. So that's the number one thing to be noticed: bitcoin is right now not scarce at all with 3600 new coins every day dumped on the market
#2 thing is: in an industry of competing alts scarcity will become mandatory - and i mean 'scarcity' ... not like 10% to 30% inflation years into adoption.
Coins will be valued according to demand and supply (of course). As long as they are scarce and useful nothing goes to zero, why should it?
I don't see what you're actually fearing because bitcoin right now is useless as money because of the megalomania which says it needs to be inflationary which turns out to be constant oversupply and loss in cap and declining interest from the public. This bitcoincommunities entire logic and idea is totally strange and actually wrong logic.
10 alts can coexists literally forever if they 1) traget different groups of consumers 2) are useful for different things 3)can each secure a demand for them 4) they are reasonably scarce (low inflation) to support their value and reduce their volatility
Bitcoins volatilty is a pain and is caused mainly by the high inflation. That inflation you got there kills it right in front of you but you seem to be all high on something so you actually don't even see that. Scalability isn't even a topic for a coin that's unable to maintain a value like bitcoin.
