Bitcoin as is, is crippled. The perfect Bitcoin has a limit on supply not the number of transactions.
Other shortcomings are peripheral.
Confirmation times are optimized for block dissemination to maintain the preferred chain. (This is a feature not a bug)
Privacy is not anonymity, the goal should be privacy we have that in Bitcoin if you want it.
Your want for Bitcoin to change are better found in an alt, why change something that predates you?. Just adopt something better. If you think it's better and if the market agrees you were correct.
SC don't peg value they peg BTC the currency, and create an opotunity to create value on another blockchain.
Proponents of SC's 1 know this and intended to profit from it or 2 don't see it and blindly support the idea.
Sidechains are the crutches that will allow it to serve all of its intended purposes.
I agree with your comment about confirmation times.
I'm not sure how you can say that privacy, on the model of the blockchain historical transaction registry and transparent ledger, is not aligned with the ability to make anonymous transactions.
I don't want Bitcoin to change, I already told you I believe it is as good as it gets (in the cryptocurrency world) from the standpoint of network, infrastructure, economic features and distribution.
Alts, while they may offer a particular desirable feature, do not come close to offering a value proposition similar to Bitcoin in regard to the features mentioned above.
I don't understand exactly what is wrong with wanting to incorporate a layer to Bitcoin so as to leverage its advantages while increasing its usability and features.
The value created on the utility sidechain is mirrored in BTC's value. I don't see how you can argue this.
