To be fair, step 4 isn't a real step, step 1 is just buying the "hub" or "border router" or whatever, and step 2 & 3 are the same for Zigbee and Matter, the button is just somewhere else.
A typical consumer has bought a zigbee hub (like they need to buy a thread border router), then use their phone to press a button in the app and then they press a button on the device. Still dead simple and doesn't require flaky bluetooth from their phone, which in 2025 most androids still suffer from.
But if you imagine a typical consumer, not a tech nerd, I think "smartphone and bluetooth" is by far preferable to your 4-step process.
