Can someone tell me what to say to someone who objects to Solaris because the supply says "unlimited" on the Solaris website?

The person who brought this up to me does have a point because a cryptocoin's value is determined by several things and one of them is scarcity.

If the supply of this coin is going to be inflated in the future, how can you say this is not going to factor into the value of the coin?

Please revolve your answer around the infinite supply issue of this coin.  Thanks,  G.P.
