You do need to separate medium of exchange from store of value. Real estate is useless as a currency while being the primary store of value for most people. Most of your objections also apply to real estate: can't know how much wheat a house is worth, houses are notoriously illiquid, price discovery is difficult and quite opaque, the sector is rife with misrepresentations. I wouldn't go so far as to say fraud, but where does "real estate agent" sit on those polls of "most trusted professions"? Houses aren't even fungible!
And if anyone thinks BTC/ETH transactions are slow and expensive (me!), around here the gas fee on real estate transactions is ~5% with a 6-month processing time...
