if we forget about backward compatibility and the impact of other types
of transactions, then the following two options would be possible:
a)
allocate only up to 10% of the space in the block for non-standard
transactions - then all senders of non-standard transactions will
compete with each other and it's only 10% with other types of
transactions. In the absence of non-standard transactions, all space of
the block will be given to standard ones. And in the absence of standard
transactions - all space of the block will be given to non-standard
ones. If bitcoin-chain was created primarily for standard transactions,
then such a model will have to be supported by the majority.
b)
change the architecture in such a way that the onchain ordinals
transaction became much more expensive, which would force them to go to
their own type of the LN - this would be a kind of justice, like the
displacement of small transactions from the onchain to the LN happening
already now
