There is also many problems with Bitcoin.
That is your mistake viewing Monero thru a Bitcoin perspective. Monero is not trying to be "global money". It's a tool for anyone that needs it and carries the spirit of the cypherpunks and white paper "p2p electronic cash" better than Bitcoin.
Monero transaction size has already been reduced by ~80% since inception. As long as the rate of adoption is equal to or below the rate of consumer tech advancement and protocol scalability improvements (this caveat applies to any crypto including Bitcoin) Monero will be fine.
An exploited inflation bug would be equally catastrophic once it happened on either Bitcoin or Monero. Attackers have the advantage. There is no good solution to fix an exploited inflation bug without hurting other users on either Bitcoin or Monero.
Did you know that an inflation bug was only discovered because of a single anonymous user? They couldve easily exploited it, but very luckily they were an honest actor who secretly let the devs know (who couldve also decided to exploit it). If they did exploit it, how would detectable inflation help after the fact? It wouldnt.
