I think, we can be confident to say that when the block subsidy will be near zero, bitcoin will be a very popular and widely used currency with very high number of users and transactions.
I would not be so confident if we start rejecting random transactions we are ideologically opposed with.
If there is a 51% network attack on Bitcoin and we can avoid it via some code modification, would you support it or not?
There is virtually nothing we can do to protect ourselves from a 51% attack other than the present game theory. Whatever you modify, so long as the attacker owns the majority of the hash rate and uses it to reverse transactions, the entire concept has practically failed.
Is there any talk about bitcoin ordinals in bitcoin whitepaper?
Is there any talk about centralized exchanges in the whitepaper? Or lightning channels? Or segwit transactions? Or coinjoin transactions? No.
The default position is that all transactions are allowed.
By the way, answer to these problems is Monero. Centralized exchanges ban Monero and Monero is also the most privacy focused currency. Move on Monero.
I am already there pal, and you should consider moving too. But that does not mean I will support censorship on bitcoin.
