A miner couldn’t practically steal coins from a chain that has the support from other miners. If a chain doesn’t have support of the miners then I guess, the chain doesn’t bring enough value to the table.

So someone's ownership of Bitcoin should be a popularity contest?
Basically a new BIP300 side chain can only be safely bootstrapped if all miners participate, making the whole BS scheme basically big blocks with more steps, but more centralizing because it cuts all other nodes out of the sidechain security model.
I don’t really understand the « beauty contest » analogy here 🤔. Not all miners need to participate. Miners will do what is in their best economic interest and #drivechains activate based on pre-defined thresholds. You’ll probably be allowed to run a #drivechain node if you want. If you don’t want to have anything to do with #drivechains, then just keep using #Bitcoin as you currently do. I don’t see what’s the problem with this.
You still need to peg in and out of the base layer. Imagine thousands of chains doing that everyday. Haven’t you learn anything from the shitty ordinals? This is Never going to get activated. If you want to shitcoin, go ahead and buy shitcoin and leave Bitcoin alone.
Bitcoin can’t scale on-chain? Maybe that’s one reason we should have drivechains…
You don’t scale on chain. You scale on L2. That’s what lightning is for. Shitcoiners forked bitcoin not because they want to scale but because they want to scam. Having drivechains will not stop all the shitcoins, it will just make bitcoin one of them.
