Not correct. Other miners can only prevent new blocks being valid, but only if they are not valid, once block is validated, that miner will include your transaction. So no, you will never have all miners refusing to inlude your transaction, while in LN hubs can be made by banks/government to block you, like they can freeze your banking account in same way. Be careful what you wish for with this LN and following Core. They are not friends of Bitcoin, they are its enemy. Only real decentralised system is the Bitcoin layer itself. Preventing it from scaling is deliberate attack on Bitcoin itself ad direct attempt on centralisation of Bitcoin users.
