If you actually mean increase block size when you said "scale", most likely it'll happen after all viable scaling option is exhausted.
That is EXACTLY what I am afraid of. Bitcoin is being treated like a hobby project not "money for the world". And what I mean by that is if we wait until all other options are exhausted we will no longer be a contender for money for the world. In other words it will be too late.
If we want to be digital gold then we will probably end up somewhere in the top 10. We will become the Peter Schiff of crypto.
