This whole question is wrong because you are only focusing on a tiny insignificant thing (fees) while there are a million different things that are much more important. For starters in 100 years from now, Bitcoin may not even exist. The cryptography used in Bitcoin is going to will have been obsolete for years by 2140, so by then Bitcoin either will have had significant changes (hard forks) that would fundamentally change it or a more probably thing is alternatives will have been invented that replace Bitcoin.

As for fees, people don't tend to use a payment system that is expensive. If that becomes regular in Bitcoin, it would kill it. That means it stops being used by regular people for payment and it will lose its "hype" and subsequently there won't be any reason for scam attacks such as Ordinals to be using the "bitcoin name".
