I think you're working from outdated info. The average Monero txn is bigger than
the average Bitcoin txn, true, but that has improved a lot over time.
While the average Bitcoin txn size is around 260 bytes, the average Monero txn size prior to the deployment of RingCT was around 2KB.
With the initial deployment of RingCT that increased to around 13KB. After the subsequent deployment of Bulletproofs to replace the previous
CT rangeproofs, the average size has now decreased back to about 3KB, and there is ongoing research into new signature schemes with
sublinear size scaling that will reduce txn sizes even further. Such improvements may deploy as early as next spring.

Mass adoption of a mass surveillance tool is worse than useless.

Monero transaction volume continues to increase https://bitinfocharts.com/comparison/monero-transactions.html
The crowd is coming. And the fact is that any new txn is hiding amongst all of the millions of preceding txns,
so it's already true there's a very large haystack for any particular needle to hide in.

Better cryptography is at least necessary, if not sufficient.

You can't replace them if you don't have a viable technology to use in their place. Bitcoin tech is not viable.

I don't see how this is true at all. Reputations matter between buyers and sellers in the real world, but not between currency sender and recipient entities on
