For taproot to rollout, you need wallet providers, exchanges, nodes and miners to agree. There are hundreds/thousands of different participants in each one of these categories across the world. Specifically, 90% of nodes need to signal for it.

Wrong, 90% of mined blocks need to signal it, not 90% of nodes. Big difference:
> at least 90% of the blocks mined in any of the designated two-week difficulty periods "signal" their support for the upgrade, then the activation process can begin. To be more precise: 1,815 out of 2,016 blocks mined within a period have to include a little piece of encoded information that indicates that the miners who mined those blocks are in favor of the upgrade.
