You're simply not going to get scalability on the base chain without sacrificing security/decentralization.
security?? um.. ASIC miners dont have hard drives, dont touch blockdata. it doesnt matter if a block is 1mb or 100mb. an asic just handles header data and a hash. (always the same size)
decentralisation?? um, we are not in the 1990's of dialup and floppy disk drives where by 1mb every 10minutes is unsustainable.
its 2021. we have 4tb hard drives and 900mb/s fibre internet.
seriously, why are you trying to push old outdated FUD propaganda to try making bitcoin appear to be useless to users.. are you really that much of a altnet fan and bitcoin hater?
..
that said. there are altnets, like sidechains and LN that have their niches. but they should not be considered as the only option people should be offramped, as a solution where people should avoid using the bitcoin network for months on end..
as THE ALTNETS have their flaws and security risks and centralisation issues.
other networks, even if branded or sloganed as being bitcoin. are not bitcoin.
having to 'federate' the coin locks in either a side chain management firm or a conglomerate of corporate LN hubs in a hub/spoke model is more risky offchain, than actually having individuals with their single signer privkey independence on the bitcoin network.
i cannot believe in 2021 people are acting like kodak in 1999 saying that digital memory wont replace 35mm picture film "cos digital storage cannot scale"
..
to answer the topic creators question
is bitcoin
TPS officially more than 7 now.
bitcoin even 4 years after SW and 12 years in total has not ever had a single day that has seen 604800 transaction (7tx/s)
7tx/s represents 4200tx every 10min. or 25200tx an hour. there has never been a single hour that has offered 25k tx.
however they have had blocks that are over 2mb but only containing silly amounts of transactions like 230tx
https://www.blockchain.com/btc/block/540107(sarcastic thankyou(real facepalm) to segwit for that bad efficiency example)
this is not because its technically/physically impossible to increase the transaction count. but is due to politics of developers saying they dont want to allow it, because they can make more profit/income from selling alternate network solutions by hampering bitcoins ability
('we dont want people buying coffee or pizza using bitcoin' (facepalm))
