Will Bitcoin become better if any of these become possible?
As we know Bitcoin is not controlled by any central authority and is not centralized. The demand and supply of Bitcoin is not controlled by anyone so no authority can control the price of Bitcoin. In any case, the point you've raised certainly won't have much of an impact on Bitcoin's price. However, the market may be slightly dumping for a temporary period, but later it will rise again.
Correct. The important point is that Bitcoin is not controlled by anyone and is not centralized, so Bitcoin will continue to be a scarce asset in the future, although many people want to prevent it from any authority, Bitcoin will still be better in the future. Bitcoin is currently only a decade old and has already had a huge impact on investors and the community. In my opinion, Bitcoin still has a long way to go to become an investment asset or hedge against inflation.
Even if what the OP said will have an impact on Bitcoin, it is only temporary, especially now that Bitcoin has passed the halving period, of course there are many dynamics going on. but believe me, Bitcoin will be much better in the future, we just need to be patient until the time comes, Bitcoin will make new history in the market.
After we know the future predictions for Bitcoin, what will we decide, whether we will participate to make a profit together or will we just be spectators and see other people's success. but the most important thing is our knowledge about bitcoin, before deciding to join, because we make sure this is for the long term, not a machine to make money in a short time, and if the time comes sooner then that is a bonus for us
