there is no such thing as a temporary government program.
witness discount? "temporary". skip the pubkey hash, cheaper tx, more txs. now forego the ability to make new witness programs. temporary. nobody will make a new one in a year. after 3 years of mempool bloat. but you can wait a year, we have schnorr with irrelevant tweaks on the secret, that isn't the spend authority.
every single move leveraging high time preference.
schnorr signatures? good.
signature aggregation? good.
raw pubkeys in outputs? why.
dropped hash layer? why.
discount still there? why.
4MB blocks via witness spam? nobody asked. just plug it with a mempool filter.
