What are you talking about? In 16 years the coinbase block subsidy is 1/16^th of today's, that's far from zero. It may still become a problem but that depends on other parameters.

Lightning isn't perfect but it's working pretty well from my own experience over some years of use. I don't know if and what experience you had with Lightning. In all the years I've been running a Lightning node I've rarely experienced forced closed channels. I never had to initiate a force close myself and can't really recall a force close from my channel partners (if they happened it wasn't a big problem for me; AFAIR the side who executes a force close pays the on-chain channel settling transaction, if I'm not the one I've no transaction fee losses due to a force close).

Kindly explain this bs sentence. I don't think you know what you're blabbering about.
