I don't know. Depends if miners and users see that drivechain as valuable to the Bitcoin ecosystem (as with any other transaction or block). Majority miners can choose not to confirm and block or transaction they wish, regardless of drivechains. Majority node operators can refuse to relay any block or TX they wish, regardless of drivechains.

Would the network accept a Kanye drivechain? Idk. If it was economically popular (in terms of BTC hashrate and volume) then it could exist. If it was harmful to Bitcoin, I doubt people would fight for its continued existence, but I don't have a crystal ball.

 But what even is a Kanye west drivechain in your mind? Any drivechain would still be BTC (trustless asynchronous 1:1). Are you just afraid of people calling their Bitcoin KanyeCoin or something? 

 Just the place where Ye holds his coin so he doesn’t have to remember his keys 

 Lol, that's a pretty funny thought. I doubt the Bitcoin ecosystem would support that L2, but Idfk, lolol 

 The drivechain folks are promising people get whatever they want. Why not? Publicity stunt might pay off 

 Yeah, tbf I don't have the best read on what people do or don't want. It could happen 🙃 

 Majority miners if they existed could not make such choices without nuking the entire L1.  A problem with DC is It gives miners who might be willing to collude a little playground where they  have fun doing reorgs and few sniping and other shenanigans without hurting the main chain. 

 Wouldn't that similarly nuke the entire notion of sidechains? If miners fucked around with L1 and chose to reorg blocks to favor a cartel of miners, then it would destroy everyone's faith in Bitcoin and people wouldn't use it.

If miners did the same to DCs, then it would destroy everyone's faith in DCs and people wouldn't use them. Bitcoin would remain unscathed.

Ofc, in either case, that's not the economically rational decision, so game theory says economically rational miners wouldn't do that. 

 It could set up a path.  One day, some miners are struggling so they decide to collude and mess around with a drivechain. Drivechain go south. A year or so later, the same miners are struggling, now they’ve already grooved the road to collusion.   People often overestimate the speed at which miner collusion would destroy the value. It wouldn’t be overnight. Plenty of time to take their profits and go do something else.
