Could BTC implement inflation and break the 21 million coin cap?

Many argue that Bitcoin at some point will have to introduce constant inflation in its protocol because at some point mining could not be profitable if the block reward found after each halving continues to drop, this is also due to the little use of its main blockchain due to the high transaction fees and increasingly high to keep Bitcoin mining afloat, Peter Todd, one of Bitcoin's most important developers, has already said that this could happen, how do you think this could affect Bitcoin and its credibility if it happens?

Mining can be still profitable even when block reward reduces by 50 percent during the halving. That's because price of bitcoins goes up after halving event. As far as the limit of 21 million coins is considered, I do not think the barrier would be broken

According to Blockstream developers, the price must rise 100% after each halving so that mining remains profitable without expanding the block size or implementing inflation in the protocol. If we do the calculations, in approximately 2070 Bitcoin would have to be worth almost 80 million dollars to be sustainable, do you see this as sustainable? Anyone would say no, so a change will have to be made in Bitcoin sooner or later.
