Now... the conversation as to what happens once the subsidy runs out? Block size, et al? Well that conversation may be worth having. But the solution does NOT lie in changing Bitcoin's monetary policy.
Subsidy includes transaction fees. If blocks get full and we do not have an increase to that size, then fees go up as well if people want to continue transacting on the base layer or L1, or require block confirmations. Those that do not, can opt to use Lightning or any of the other second layer solutions, decentralized or centralized, it does not matter all that much.
Most of the whole world are happily transacting using debit cards and credit cards or even points or miles or other loyalty rewards. I get my coffee from McDonald's using a card with stickers! And then I get another sticker back. I get my french fries using this monopoly looking coupon that I found.
Apples. Hoes. Stickers. Coupons. Bitcoins? Sats? It's only a matter of time.
We have decades before the base block reward goes below 1 sat in 2140-ish. Effectively, we will know by 2036 to 2040 what is going to be the template for the rest of the future as 99% of all bitcoins will have been mined then and the next hundred years is a fight for the last 1 percent.
