You can't say "store of value(price)" because a commodity like bitcoin, if its value was stable, its price would NOT be stable.
You are saying, that if we don't guard bitcoin's transactability, then it won't act like gold (ie fairly stable value), but there is no founded scientific argument for this, and in fact bitcoin's "utilitiy" in regard to tps already functions far better than gold. It is and always will be, even with 1mb, cheaper and easier to transact with bitcoin than gold.
The tps a 3/sec does not hurt bitcoin's properties as a store of value. Thats a tacit assumption.
2 things
1. bitcoin is not inflationary (to address your many earlier points that still gripe me)
2. bitcoin is not a commodity. its an asset.
a commodity is a raw material used to make other products
beef=hamburgers, steaks
oil=plastic, fuel
wheat=bread, animal feed
gold=jewellery/circuits
gold sits in 2 categories and on multiple markets. 1 being the commodity market (jewellery/circuitry). the other being asset market.
just because you see bitcoin as the similar principles of golds ASSET values. does not mean bitcoin also holds golds commodity value.
they are 2 separate categories.
you are also mixing up golds value(utility/desire) to fit whatever narrative you like.
golds value(price) is a culmination of desire(asset store of value) AND utility(commodity usefulness as jewelery and circults)
take away golds commodity utility.. and people only value(desire price) it as the equivalent of rust.
take away bitcoins ability to be spendable to pay rent once a week or groceries once a week. and you affect its utility and desire. making its store of value(price) deminish
