All BTC privacy technologies will be opt-in, and all empirical evidence shows this doesnt work - both from a technical and sociological perspective. On the technical side, analysis is always much more difficult to stop than people think. In terms of people's behaviour, adoption is nearly impossible and services will ban or flag such transactions, if mining pools even mine the transaction.
Sure grandma can just practice output control (that I still struggle with after using BTC for 8+ years) and pay hundreds in fees for coinjoins with every transaction, problem solved /s

I only see papers finding flaws that prevent it from being private, and that people are struggling to get it to work even without thinking about privacy. Scaling is still a difficult and unsolved problem for now, lets not make absurd privacy claims alongside it. Relying on Tor is an issue in itself.
The problem is not that the technologies are opt-in. The problem is that there is no simple UI implementation at this point in time. In the end any anonymized Lightning Wallet transaction will be just as simple as scanning a QR code with a simple slider that lets you choose the level of anonymity. And the ability to "opt-in" will give the market the opportunity to properly price anonymity. This is a feature not a bug.

Scaling is essentially a solved problem thanks to Lightning. Adoption is currently a problem but will become a non-problem as soon as transaction fees rise so much that it is worth the effort for everyone to get Lightning Network running. Right now this is not the case.
It speaks for itself that yours is a very fringe opinion: none of these claims are strongly supported with evidence at this point of time.
Saying the privacy properties are already solved and settled is ridiculous, none of the literature or other information supports that
Only a fool would say it is certain that everyone will have magic instant, scalable, cheap, perfectly private btc transactions and it's already solved and settled
